Nanomaterials exhibit many exotic properties that traditional materials do not have. The first thing we need to know is that the nanometer (mainly refers to less than 100nm) of the composition of nanomaterials has four major effects: 1. Small size effect The boundary conditions of the crystal periodicity are destroyed; the atomic density near the surface layer of the amorphous nanoparticle decreas...

The size of the particles is called the particle size of the particles, which may also be referred to as particle size. Particle size or particle size refers to particle diameter. Of course, for non-spherical particles, the particle size is related to the measurement criteria and statistical methods, and the particle size can only be "equivalent". The percentage (or cumulative percentage) of parti...

In the world of electronic materials there are two important material properties "electrical conductivity" and "thermal conductivity". Generally speaking, as long as the electrical conductivity of the material is good enough, the thermal conductivity is also good. For example, copper, silver, aluminum and other metal materials have good electrical and thermal conductivity. Therefore, most metal ma...

Boron carbide, also known as black diamond, is an inorganic substance with a chemical formula of B4C, usually a gray-black micropowder. It is one of the three hardest known materials (after diamond and cubic boron nitride) and is used in tank armor, body armor and many industrial applications. Several preparation methods of nano-boron carbide (supply 100-200nm): 1. Carbothermal reduction method Be...

Nano zinc oxide is a good vulcanization activator. Since nano-zinc oxide can be combined with rubber molecules at the molecular level, it can improve the performance of the rubber compound and improve the characteristics of the finished product. Take radial tires and other rubber products as examples. The use of nano-zinc oxide can significantly improve the thermal conductivity, wear resistance, t...

The formation of a stable dispersion system, in addition to using electrostatic repulsion, that is, the negative charges adsorbed on the surface of the particles repel each other, to prevent the adsorption/aggregation between particles and finally form large particles and stratify/settlement, but also use. The theory of the steric hindrance effect, whereby particles that have adsorbed negative cha...

Nano technology spans multiple disciplines, involving a wide range of faces, and has had huge impacts in many areas and even the entire social life, such as in the fields of physics, chemistry, material science, biology, medicine, engineering, and computer simulation. Nano particles appeared in the 1980s, that is, pink particles with a particle size of less than 100nm. Because of the small nanopar...

The polymer film material has good processing and electrical insulation, and is widely used in various fields of industrial production and daily life. However, due to its high surface resistance, static electricity is easy to accumulate during use. When static electricity accumulates to a certain degree It will cause static vacuums, electric shock, and even adverse consequences such as fire and ex...
