Abstract
The invention relates to a method for preparing nylon-PEDOT (poly(3,4-ethylenedioxythiophene)) compound conductive fabric through in-situ polymerization. The method comprises the following steps of: 1) pretreating a nylon fabric by using acidic solution, and padding the nylon fabric for times, wherein the dipping time is 5-15 minutes and the padding residual rate is 60-90 percent; and 2) dipping the nylon fabric in mixed solution containing ferric chloride, sodium polystyrenesulfonate and 3, 4-ethylenedioxythiophene (EDOT), keeping reaction temperature to be 30-90DEG C, keeping reaction time to be 1-20h, and after reaction is ended, taking out, washing and drying the fabric to obtain the nylon-PEDOT compound conductive fabric. By adopting the method, in combination with a padding technology which is commonly used for dyeing and finishing, the PEDOT can be enabled to rapidly enter the internal part of nylon fibers, the reaction time is shortened and the environmental pollution is small; and the nylon-PEDOT compound conductive fabric can be applied to the fields of textile chemical sensing and biological remediation materials, electromagnetic shielding materials and the like.
