What are the main approaches to obtain electrically conductive polymer fibers ... 

Other Applications. Thus far the phosphazene fluoroelastomers (PNF) and aryloxyphosphazene elastomers (APN) have moved to the commercial stage. In addition to elastomers, phosphazenes are being investigated as fluids, resins and plastics. Other areas which hold promise include fire resistant paints (55), fiber blends and additives, agrichemicals and herbicides, drug release agents and electrically conducting polymers (6). 

HDPE, composite materials such as epoxy-glass fiber and epoxy-carbon fiber, and laminate structures such as polymer films on bulk metal substrates. Thin-conductive film heaters were made of electrically conductive paints, electrically conductive polymer films, metal foils (stainless-steel, copper, titanium, and titanium alloys), and thin metal films sputtered on a ceramics or glass. The samples dimensions varied from a few centimeters to 5m.

The electrically conductive polymers have their greatest use in EMI-shielded casings and protective housings of electronic and telecommunications equipment, where they have rapidly substituted metal because of their low weight and easy workability. Steel fiber is mostly used in filled conductive polymers intended for EMI-shielding applications, which will be discussed below. 

Previously disclosed methods of preparing electrically conductive aramid fibers depend on cospinning the poly-p-phenylene terephthalamide with intrinsically conductive polymers such as polyaniline. However, these methods yield fibers with much higher... 

Applications of Electrically Conductive Inherently Conducting Polymer Fibers and Fabrics... 

Conducting polymer fibers were prepared by melt mixing and chemical coating on fibers. Different conductive materials were used in order to obtain conductive PP-based fibers with specific electrical and mechanical properties. The electrical conductivity and morphological characteristics of these fibers were investigated (Kim et al. 2004). The conductive fibers are intended for use in creating conductive yams, conductive fabrics (which can be used as electromagnetic shields), and multifunctional textile stractures for novel applications.

A composite comprising paper and a conducting polymer can be prepared by impregnation of paper with a solution of a precursor polymer and heat treating the coated paper. The electrically conducting polymer is located on the surface or between the fibers of the paper [885]. Sexithiophene and other oligo(thiophene)s are ideal photochromic materials for efficient and ultrafast incoherent-to-coherent optical converters [886].
