Adsorption at the liquid-solid interface is widely used by the textile industry in processes such as dyeing, finishing, wastewater treatment, and many others. Precipitates of nano dimensions formed in situ have been used to form coherent, usually amorphous, films of metal oxides, sulfides, etc. on solid surfaces including textiles. This phenomena has been successfully used to polymerize pyrrole on the surface of textile fibers, fabrics, or yarns. While pyrrole is particularly suitable for this process, other monomers such as aniline or thiophene may be used, Polypyrrole is one of the more environmentally stable conductive materials and the above process has been successfully used in industrial production. The electrical properties and the environmental stability of the product depend on a number of variables such as concentration of the chemicals and particularly the dopants used. Furthermore, the environmental stability of the conductive textiles can be significantly improved by the use of certain additives in the polymerization. Numerous applications have been found for conductive textiles, especially in the field where their microwave adsorption characteristics are highly desirable. This is the case in military applications like camouflage and stealth technology.
