摘要

The chemical grafting of polyaniline, poly(oanisidine), and poly(o-toluidine) on polyester fabric was carried out with ammonium peroxodisulfate in an acidic medium. The formation of the grafted fabric substrate was confirmed with reflectance spectroscopy, Fourier transform infrared spectroscopy, weight-loss studies, and conductivity measurements. The grafting percentage and efficiency percentage were determined for the different grafted substrates. The thermal and flame-retardant properties of these grafted substrates were elucidated. Thermogravimetric analysis thermograms and derivative thermogravimetry curves showed that the grafted substrates had a higher thermal stability and char-residue percentage at 700degreesC. The grafted substrates showed a higher activation energy of thermal decomposition than the nongrafted substrates. The grafted substrates showed good flame retardancy, which was evident from the increase in the limited oxygen index in comparison with that of the nongrafted substrate.
