摘要

In this experiment, the polyaniline coated fabrics were produced using aniline as the monomer by in-situ polymerization, p-toluenesulfonic acid as the doping agent and ammonium persulfate as the oxidant on the polyester fabric. The influence of different process conditions on the dielectric properties of the polyaniline coated fabric was explored. The fastness to rubbing of the coated fabrics was tested. The results show that the concentration of aniline and the oxidant both influence the dielectric properties of the fabrics. An appropriate aniline concentration is beneficial to increase the output of the polyaniline and reduce sudden and violent polymerization. A suitable oxidant concentration is beneficial to form polyaniline with a complete structure, reducing the occurrence of peroxide. When the aniline concentration was 0.4 mol/L and the oxidant concentration was 0.4 similar to 0.5 mol/L, the polarizing ability, loss ability and absorbing-attenuation ability of the fabrics to electromagnetic waves are all stronger. The dielectric properties of the obtained polyaniline coated fabrics varied corresponding to different types of dopants and doping levels. Compared to glacial acetic acid, hydrochloric acid and nitric acid, the dielectric properties of the prepared coated fabric were optimal when using p-toluenesulfonic acid as the dopant. When the concentration of the p-toluenesulfonic acid was 0.2 mol/L, the polarizing, loss and absorbing-attenuation abilities of the fabrics to electromagnetic waves are all stronger.
