A b s t r a c tCotton fabric was modified with 1,2,3,4-butane tetracarboxylic acid (BTCA) as cross-linking agent in presence of sodium hypophosphite (SHP) as catalyst. Polypyrrole-Zinc oxide (ppy-ZnO) and polypyrrole-Zinc oxide-carbon nanotube (ppy-ZnO-CNT) composites were also prepared by in-situ chemical polymerization method. The composite sol was coated on cotton fabric using pad-dry-cure technique. This coated cotton fabric was characterized by FE-SEM with EDAX, XRD, UV-DRS and FT-IR analyses. Flame retardant and UV-protection properties of the coated cotton fabric was tested and compared with uncoated fabric. ppy-ZnO-CNT composite coated cotton was found to possess better properties than with uncoated cotton.
