Preparation of Conducting Composite Materials Based on Polymer Nanofibers and Polypyrrole

Resumo

Conducting materials based on polypyrrole-modified nanofibers of polylactides of different molecular masses and copolymers of ε-caprolactam (–NH–(CH₂)₅–CO–) and hexamethylenediamine adipate (–H(CH₂)₆NHCO(CH₂)₄CO–) were prepared. As shown by scanning electron microscopy, oxidative polymerization of pyrrole on the polymer nanofiber matrix depends on the nanofib er hydrophilicity. The heterophase synthesis of polypyrrole on the surface of hydrophilic nanofibers of the aliphatic copolyamide allowed uniform coating of the material surface with polypyrrole nanoparticles. The surface resistivity of the composite material was about 0.4 kΩ sq^–1.
