摘要

The process of diffusion polymerization in a mixed bath is used to produce the electrically resistant fabrics such as the polyester, polyester/viscose, viscose, Bamboo, Bamboo/cotton and cotton fabrics and it is done by the in situ chemical oxidative polymerization of conductive polyaniline (PANI) polymer having ammonium persulphate as the oxidant. The electrical resistance of the fabrics have been measured with the help of D.C. regulated variable power supply unit by varying the gauge length from 1”, 2” and 3” and input voltage from 20V to 160V. The polyaniline coating evenness was investigated by using Scanning Electron Microscopy (SEM). The test result shows that the electrical resistance decreases with increase in the gauge length and the input voltage and also fabric cover factorshave playing an important role on electrical resistance of the fabrics. The polyaniline coated cotton fabric has less electrical resistance than the polyaniline coated fabrics of the polyester, polyester/viscose, viscose, Bamboo, Bamboo/cotton. The cotton and cotton blend fabrics surface have absorbed more polyaniline particles and hence show more depositions over their surface when compared to that of bamboo, polyester, polyester/viscose and viscose.
