The first thing that comes to people's minds is that diamonds are radiant and sparkle. Would you recognize them if they were reduced to tiny particles, even microns and nanometers?
Nano diamond, the appearance of humble, but has a strong, multifunctional connotation.
First, let's talk about nanotechnology.It is no exaggeration to say that the 21st century is the nano century, and the development of nanotechnology is as far-reaching as that of the industrial revolution in the 18th century.Any material small to the nanoscale, its properties will take a leap forward.Because the nanometer material has small particle size, large specific surface area, high surface energy and surface characteristics such as large proportion of atom, and the characteristic of the four effects: small size effect, quantum size effect, quantum tunnel effect and surface effect, thus has the traditional materials don't have strange or unusual physical and chemical properties.
Nano diamond is one of the typical materials, which not only has the inherent high hardness, high hardness, high corrosion resistance, high thermal conductivity and other traditional properties of diamond, but also has the unique characteristics of nano materials.
At present, there are three main preparation methods of nano-diamond: static pressure synthesis, diamond single crystal grinding and detonation, which have been used in industrial production.
Detonation synthesis of nano diamond production efficiency is relatively high, compared with other synthetic methods, the personality is bright, more apparently more adapt to the modern industrial production, usually in the preparation method of explosive for the first body of TNT and RDX explosives (used as raw material), namely in the detonation instantaneous high temperature and high pressure conditions, the use of negative oxygen balance explosives wasn't by oxidation of carbon atoms in the detonation, after gathering, crystallization and a series of physical and chemical process, the formation of the nanoscale carbon particles group, including diamond, graphite and amorphous carbon.By removing the non-diamond carbon phase with oxidant, the nanodiamond was obtained. The recovery rate was about 8~10% of the mass of the explosive used, and the diamond particle size was 5~10nm. After chemical purification, the purity was about 95~97%.
The structure and nature of the material determine its use.
Application of nanometer diamond performance can be divided into two parts, the surface and nuclear, nanometer particle surface performance, which make use of its performance, the small particle size, large specific surface area, high surface energy, large proportion of surface atoms and the characteristic of the four effects: small size effect, quantum size effect, quantum tunnel effect and surface effect.The core's properties mainly take advantage of diamond's superhard material properties, semiconductor residual heat conduction and heat dissipation characteristics, wide potential...
Therefore, nano diamond has been widely used.At present, nano-diamond is mainly used in the following aspects:
(1) Ultramicro diamond CVD method synthesized by detonation was used to prepare diamond films;
(2) Research on ultramicro diamond used in chemical composite plating;
(3) Used for lubricating oil, solid lubricant and lubricating coolant;
(4) Sintered body;
(5) Possibility of infrared and microwave absorption materials:
(6) Nano-diamond is used in magnetic recording system;
(7) For catalytic stealth materials;
(8) Nano-diamond can be added to rubber and polymer to improve its performance;
(9) Nano-diamond can be added to the explosive to improve the explosive power;
(11) Nano-diamond is added to fuel oil.The dispersion and combustion value of fuel can be improved.
(12) Nano diamond battery
(13) The application of nano-diamond in biomedicine
(14) Nano-diamond is applied in the field of environmental protection
(15) Ultra-precision polishing (16) Power generation energy storage
Ultra-precision polishing -- the mission of the modern electronics industry
With the advent of 5G communication era, electronic components have been deepening towards the direction of large scale, high integration, high power and small size. Ultra-precision polishing process is crucial in modern manufacturing industry.The mission of ultra-precision polishing in the modern electronics industry is not only to flatten different materials, but also to flatten multiple layers of material so that a 'global flatten' of a few millimetres of silicon wafers can form very large scale integrated circuits consisting of tens of thousands to millions of transistors.It is also widely used in integrated circuit manufacturing, medical equipment, auto parts, digital parts, precision mold, aerospace fields.This is enough to explain the ultra-precision polishing process, is the "soul of technology", is listed in the neck technology list, the United States and Japan firmly grasp the initiative of the global market, how to break through this technology, the material is also the key!
Excellent steel - Neck technology problem
Whether it is aviation steel or high-end bearing steel, China's manufacturing industry is a short board, is a neck technical problem.As the indispensable core of industrial manufacturing, how to complement China's manufacturing industry, excellent steel is the key!
Diamond particle reinforced steel matrix composites (diamond super nanometer steel family) have many advantages such as ultra-high hardness, ultra-high strength, ultra-wear resistance, ultra-low friction coefficient, high impact toughness, high thermal conductivity, high cost performance and so on.If the nanoparticle diamond can be diffused into the steel through certain experimental conditions, the microstructure and mechanical properties of the diamond will be greatly affected.If this scientific research achievement can be industrialized and produced in large quantities, it will certainly lead to an epoch-making revolutionary change in the fields of strategic basic materials, strategic frontier materials, high-end machinery and equipment manufacturing, and advanced surface engineering, and the appearance of China's basic manufacturing industry will certainly be changed!
Nanomedicine -- an important development direction of modern medicine
In 2020, with the outbreak of the epidemic, people's understanding of life has been strengthened, and their demands for health and medical technology have been constantly raised.
Nanomedicine has become an important development direction of modern medical treatment.Currently, nanotechnology has been successfully used in the detection and treatment of various diseases, and the U.S. FDA has approved more than 60 drug applications containing nanomaterials.In the medical field, "early detection, early treatment" has become a medical common sense, but the accuracy and accuracy of traditional detection technology are difficult to achieve the purpose of "early detection".As a result, many medical innovation companies are turning to nanotechnology in the detection and diagnosis of diseases.
Nano-diamond has been attracting much attention. Due to its properties of large specific surface area and surface multi-functional groups, it can adsorb small molecules and large biomolecules through hydrophilic/hydrophobic interaction and electrostatic force, etc., and has important development significance in the field of biomedical science.In recent years, scientists have also been actively utilizing the unique inertia, biocompatibility and functional engineering design characteristics of nano-diamond particles in the field of medicine, including drug delivery, labeling, protein separation, anti-cancer treatment, sterilization and other aspects.
Energy storage and Environmental Protection -- an important strategy for sustainable development
Energy storage is a national key strategy.Diamonds also shine in energy storage.Recently, NDB, a California company, announced the development of a 28,000-year nano diamond, which completely changes the energy equation!And if one part of the battery fails, the active nanodiamond part can be recycled into another battery for reuse.This also means that this invention has the potential to solve the world's major carbon emission problem!Power generation is entering the "Diamond Age"!
In addition, nano-diamond films have excellent field emission properties, and their field emission intensity is much higher.This is due to the small grain size and low threshold voltage of nano-diamond film, which makes it easy to emit electrons from the film.The cold-cathode emission performance of nano-diamond film is far better than that of micron diamond film. As a field emission device, nano-diamond film is not only efficient, but also can greatly reduce the production cost and energy consumption.In general, nano-diamond film has the potential to be an important material for preparing the next generation of flat display.
Nano-diamond has excellent electrical properties, high thermal conductivity, wide band gap width and high carrier mobility, which makes its application in semiconductor field have great potential.
Nano-diamond has excellent performance and wide application range. So far, its application in many fields is still in the initial stage and cannot be widely used in a short period of time.But we believe that materials will change lives, and the future of nano-diamond is worth everyone's expectation.
Based on this, Carbontech 2020 Diamond Forum will be held in Shanghai International Purchasing Convention and Exhibition Center from November 17 to 20.The forum will focus on the innovative applications of diamond in health care, ecological environment, semiconductor devices, heat conduction and heat dissipation, jewelry, etc. Global industry giants, top scientific research teams, academic representatives and enterprise representatives will be invited to participate in the forum, so as to carry out scientific research and academic exchanges and promote the prosperity and development of the industry.
