Effect of RF plasma modification on electrical characteristics of collagen containing polymer materials surface

Artificial materials that used in the manufacture of textile industry products have increased static characteristic and electrical resistivity. The large electrical charge accumulated by them negatively affects the human body. The use of natural collagen containing polymer materials is the safest way to avoid unacceptable risk to human health. With the help of nonequilibrium low temperature plasma (NLTP) treatment of collagen materials under reduced pressure it is possible to achieve an additional reduction of the electric potential by scattering charges on the surface of genuine leather. Under certain conditions the main reason for the generation and accumulation of static electricity is the high hygroscopicity of the material. Hydrophobization of the surface of collagen containing materials is achieved through the use of a hydrophobizator and volumetric NLTP treatment. Plasma treatment of collagen containing polymer materials also increases their biological compatibility and antimicrobial properties, improving mechanical characteristics by changing the internal structure of the material.
