Chemical oxidative grafting of conducting poly(N‐methyl aniline) onto poly(ethylene terepthalate)

Abstract

Detailed studies on the peroxidisulfate (PDS) initiated graft copolymerization of N-methyl aniline (NMA) with poly(ethylene terepthalate) (PET) were carried out in p-tolene sulfonic acid medium under nitrogen atmosphere. Experiments were designed to follow the rate of formation R h of the poly(N-methyl aniline (PNMA), simultaneously with the rate of grafting of PNMA onto PET. Effects of concentration of NMA, PDS, PET, time, and temperature on R h and graft parameters were followed. Kinetic equations were deduced to correlate the changes in the rate with experimental conditions. Graft copolymers were isolated and grafting of PNMA onto PET was confirmed through FTIR, thermogravimetric analysis, and conductivity measurements. Tensile measurements showed that grafting of PNMA did not alter the tensile properties of PET. © 2004 Wiley Periodicals, Inc. J Appl Polym Sci 95: 596 -605, 2005

Preparation and Characterization of Conducting Poly(ethylene terephthalate)/Polypyrrole Composite Fibers

“…Polypyrrole (PPy) [1,2,5], polyaniline [6,7] and their derivatives [8,9] are much more preferred as conducting polymers for the preparation of synthetic fibers/conducting polymers. Among the conducting polymers, PPy has some advantages over the other conducting polymers due to its superior properties such as higher conductivity, environmental stability, and easy synthesis [10,11].…”
