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...

In the process of powder storage, transportation and use, it is often hoped that the nano-aluminum powder exhibits low activity and is less affected by external environmental factors (temperature, humidity, etc.), so that the product has stable performance for a long time. On the other hand, it is desirable to exhibit high activity in solid rocket propellants to obtain high energy release rate and...

Dispersant is a kind of surfactant that has two opposite properties of lipophilicity and hydrophilicity in the molecule. It can increase the compatibility of oily and aqueous components in the same system, and also prevent the sedimentation and agglomeration of particles, forming an amphiphilic reagent required for stable suspensions. Dispersant, also known as wetting dispersant, has many kinds. A...

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...
