Ionic interactions in polyacrylonitrile/polypyrrole conducting polymer composite

Abstract

A conducting polymer composite was prepared by the postpolymerization of pyrrole in a polyacrylonitrile (PAN) matrix film. To enhance the electrostatic interaction between the two phases, a small amount of a sulfonate (SO 3 Ϫ ) or a carboxylate (COO Ϫ ) group was incorporated into the PAN structure. The presence of electrostatic interaction between the conducting polypyrrole and the anion-containing PAN copolymer was elucidated by examination of the morphology and the electrical properties of the composite. The aromatic sulfonate-containing matrix provided the composite with the best results in the electrical conductivity, the environmental stability of conductivity, and the morphological property.

Conductive polymers/polyacrylonitrile composite fibers: Fabrication and properties

“…In the past years, some scholars have prepared several conductive fibers via chemical and electrochemical polymerization of conjugated monomers on nonconductive polyethylene, nylon or poly (ethylene terephthalate) fibers [11][12][13], or by melt spinning and coating conductive materials on the surface of polypropylene [14]. However, investigations on polyacrylonitrile (PAN)/conductive conjugated polymers composite materials have mainly focused on preparing conductive film [15][16][17][18][19], but scarcely on PAN fiber. PAN fiber is a copolymer composed of the first monomer of acrylonitrile and the second monomer of vinyl acetate.…”

Polypyrrole/Poly(acrylonitrile‐co‐butyl acrylate) Composite

“…Moreover, acrylic fiber dyes very well and has excellent colorfastness. AN copolymers were used as polymer electrolytes, i.e., in Li‐polymer batteries,2–8 to produce conductive composites as thin films,9–11 or used as a fiber form,12, 13 with addition of salts or self‐dopant polymers to improve the electronic interaction of structure and dielectric and conductance properties. Electrostatic interaction increases by incorporation of a small amount of a sulfonate (SO 3 − ) or a carboxylate (COO − ) group in such composites, resulting in better electrical conductivity and improved morphologic properties.…”
