Surface modification treatment of inorganic and organic materials by plasma surface cleaning system:
Due to the in-depth development and application of porous materials, more and more porous materials use plasma surface cleaning system for surface modification. Today, we mainly introduce the surface modification technology of plasma surface cleaning system, and introduce some application examples in combination with the actual situation for everyone For reference, I hope it helps everyone. This article takes porous silicon materials and activated carbon materials as examples to introduce the surface modification treatment technology of organic and inorganic porous materials.

plasma surface cleaning system
1. Porous silicon material:
The plasma surface cleaning system uses nitrogen plasma to plasma-modify the porous silicon material, which can maintain the pore structure of the porous silicon material, improve the light transmission effect, and reduce the light absorption loss. At the same time, it will also have a certain impact on the internal silicon atoms. In terms of refractive index, plasma surface modification will have a certain impact on it.
2. Activated carbon material:
The plasma surface cleaning system is used to modify the granular activated carbon. Although the surface area of ​​the activated carbon is reduced, the number of macropores on the surface will be increased, and the concentration of surface acidic functional groups will be increased to make it more resistant to metal ions such as copper ions and zinc ions. Increase the adsorption capacity of the material, thereby increasing the adsorption capacity of the material:
Used for organic porous materials, including but not limited to the following aspects.
1. Porous ultrafiltration high polymer film:
The use of plasma surface cleaning system to treat porous ultrafiltration polymer membranes can increase the surface tension and hydrophilicity of the membranes, improve the filtration performance of the ultrafiltration membranes for buffers and protein components, and improve the filtration indicators of the membranes. Through plasma surface modification, the pore size and porosity of the ultrafiltration membrane can be increased.
2. Two or more synthetic fiber materials:
The plasma surface cleaning system is used to oxidize the surface of synthetic fiber materials, which can increase the oxygen content on the surface of the fiber and enhance the hydrophilicity of the fiber. In addition, in the plasma, high-energy ions will bombard the surface of the fiber, which may slightly decrease its tensile strength.
