Abstract
An anti-corrosive polymeric complex which is comprised of a plurality of double-stranded molecular complexes. Each of the molecular complexes are comprised of a strand of a conductive polymer and a strand of a copolymer. The strands of the polymeric complex are non-covalently bonded to each other along the contour of the strands to form a side-by-side, twisted, double-stranded configuration.
Claims4
An anti-corrosive polymeric complex which comprises:
- a plurality of double stranded molecular complexes, each of the molecular complexes comprising a strand of a conductive polymer selected from the group consisting of polyaniline, polypyrrole, polythiophene, poly(phenylene sulfide), poly(p-phenylene), poly(phenylene vinylene), poly (furylene vinylene), poly(carbazole), poly(thienylene vinylene), polyacetylene, and poly(isothianaphthene),
- and a strand of a copolymer, the copolymer selected from the group consisting of poly(acrylic acid-co-methylacrylate), poly(acrylic acid-co-ethylacrylate), poly(acrylic acid-co-acrylamide), poly(acrylic acid-co-methylvinylether) and poly(acrylic acid-co-ethylvinylether), the strands of the polymeric complex being non-covalently bonded to each other along the contour of the strands to form a side by side, twisted, double stranded configuration, the polymeric complex being organic solvent soluble.
