▎ 摘  要

NOVELTY - Nano additive coating method for imparting high electrical conductivity to non-conductive textiles/fabrics, involves dispersing 0.1-0.5 g dried oxidized single-walled carbon nanotube in distilled water for 30-180 minutes with an ultrasonic mixer. The nanotubes are prepared by adding surfactant such that the ratio of oxidized to single wall is 1:1-1:10 by weight, and by mixing with a magnetic stirrer at low speed for almost 10-60 minutes until foaming ends. The textiles/fabrics are coated with graphene oxide by immersion in a suspension of graphene oxide and then with a single wall carbon nano-tube immersed in the suspension of single wall. USE - The method is useful for nano additive coating for imparting high electrical conductivity to non-conductive textiles/fabrics conductive textile/fabric, which is used in radar absorber systems, lossy dielectric (resistor) and/or magnetic composite materials to prevent back reflection of microwave radiation. ADVANTAGE - The method increases the electrical conductivity of fibers and fabrics using coating solutions with adjusted surface tension and nanomaterial content by the application of two-dimensional nano materials including graphene and carbon nanotubes to the surfaces of electrically non-conductive glass/quartz/basalt, polyester, nylon-based continuous or chopped fibers and/or their woven/nonwoven fabrics in single or hybrid configurations, without changing the surface chemistry. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the conductive textile/fabric.
