A Facile Route for Fabrication of Conductive Hydrophobic Textile Materials Using N-octyl/N-perfluorohexyl Substituted Polypyrrole

Abstract

A novel N-octyl/N-perfluorohexyl substituted pyrrole was synthesized by reacting pyrrole with octyl bromide or perfluorohexyl iodide and their polymers were formed on cotton and silk textiles to make them conductive and water-repellent. Results revealed that pyrrole has been successfully transformed to N-octyl/perfluorohexyl pyrrole and complete substitution was obtained with reaction of octyl bromide. Scanning electron microscope images demonstrated that a film of N-substituted polypyrrole is homogenously covered around the fibers. Poly N-octyl/perfluorohexyl pyrrole covered cotton and silk fabrics imposed electrical conductance and hydrophobicity properties, simultaneously. The highest CA of 147.1° was obtained in the case of poly N-octyl pyrrole coated cotton fabric.
