Modification of PAN-fibrous materials by metallization of their surface
The paper establishes prospects for the application of surface modification of fibrous materials based on polyacrylonitrile by their chemical metallization. The modes and compositions of solutions of electrolytes of chemical metallization of PAN-TJ materials have been worked out in the work, which make it possible to obtain strong coatings uniform along the entire length of the fibrous material, having a characteristic color of the coated metal and good adhesion. The results of this study confirm the feasibility of carrying out the degreasing process of PAN-fibrous materials at a temperature of 60 °C, since at this temperature there is the least reduction in the breaking load of copper-coated PAN-fibrous materials while maintaining the ability to deform. The proposed technology of metallization of fibrous materials based on PAN in a low-component electrolyte is promising, while reducing environmental stress due to the absence of harmful electrolyte components (acids during etching) and washing waters. Metallized fabric using an alternative technology can be used as a protective shield against radiation of electromagnetic waves of the radio frequency range from 30 Hz to 3000 GHz.
