Abstract

A simple and effective surface modification of polyester fabrics with sulfuric acid to improve the interfacial deposition of polypyrrole was presented in our work. A range of sulfuric acid concentrations were analyzed by studying water contact angle. Effect of sulfuric acid modification on the deposition of polypyrrole was investigated by sheet resistance and color depth of fabric samples. Polyester fabrics coated with polypyrrole layer were confirmed by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), X-Ray diffraction spectra (XRD), Fourier transform infrared spectroscopy (FTIR). XPS showed that sulphur containing functional groups were obviously appeared on the polyester fiber surface after modification, which were advantageous to promote the deposition of polypyrrole onto polyester fabrics. The improved deposition increased electrical conductivity of fabric samples.

Comment: Novelty
The polyester (PET) fabrics coated with polypyrrole (PPy) have been investigated extensively as conductive textiles in recent years. However, the poor deposition of PPy on PET fabrics limits its applications. Many attempts have been made to overcome the problem, for example, plasma treatment and layer by layer self-assembly technology. Most of these methods are difficult to be used at a mass production scale. In our work, PET fabrics were modified with H2SO4 at high temperature prior to forming PPy layer via chemical oxidative polymerization. This modification can obviously improve both the deposition of polypyrrole (PPy) on the polyester (PET) fabrics and electrical conductivity. Compared with other methods, modification with H2SO4 is simpler to perform and is more appropriate for industrial production.
