Abstract: In this study, 2-methacryloyloxyethyl phosphorylcholine monomer has been polymerized using azobis-isobutyronitrile initiator on the surface of cotton fabric by admicellar polymerization with the assistance of anionic surfactant (dodecylbenzenesulphonic acid sodium salt) along with NaCl as electrolyte. The polymeric film formed on cotton surface has been characterized by FTIR and SEM. FTIR spectrum shows additional bands at 1720 cm-1 (C O str.), 1258 cm-1 (P O str.) and 1078 cm-1 (P ̶̶ O ̶̶ C str.) of phosphorus based polymer formed on cotton fabric. Thermal behaviour in nitrogen atmosphere is also studied which shows that onset temperature of degradation of treated cotton fabric decreases by 37 ºC and char yield increases by 21.7% at 600 ºC. The burning behaviour of treated cotton fabric is investigated by 45º auto flammability and limiting oxygen index tests. The pure cotton fabric burns the entire length of 15 cm sample in 11.8 s but treated cotton fabric self-extinguishes in auto flammability test. The durability of treated cotton fabric has also been studied up to two home launderings.
