“…The measurements attributed to 24 h after polymerization. It seems that surface electrical resistance decreases with increase in reaction time, temperature, and oxidant concentration is derived from thicker coating layer 23. This is proved by the darker reddish‐brown color of P3MT‐coated polyester prepared in higher reaction time, temperature, and oxidant concentration.…”

“…As the data shown, the decreasing of electrical resistance of P3MT‐coated polyester from 10 9 to 10 15 Ω to at least around 10 3 –10 6 Ω is because of coating a homogenous thin layer of high conductive polymer particles on the surface. Table I shows the effects of the reaction duration (time; 2, 5, and 8 h) and temperature (0, 25, and 40°C) and oxidant concentration (0.2, 0.6, and 1 M ) on the surface electrical resistance 16, 23. The measurements attributed to 24 h after polymerization.…”

Poly(3-methylthiophene) (P3MT)-coated polyester fabric is a conductive textile with specific electrical and optical properties; for instance, color change under external stimulus (chromic behavior) was successfully prepared by chemical polymerization with continuous, speed stirring technique. To investigate the striking effect of some variable conditions of polymerization process, the effect of reaction time, temperature, and oxidant concentration on conductivity of the P3MT-coated fabric was studied. Scanning electron microscopy confirmed that the surface of fabric has entirely been coated with P3MT particles. The further characterizations were investigated using Fourier transform infrared spectroscopy to provide evidence of forming particles onto the fabric, UV-vis absorption spectroscopy, electrical surface resistivity, and pressure dependence visible reflectance spectrophotometer measurements and X-ray diffraction analysis. The blue shift in wavelength of maximum absorption of about 95 nm to a longer wavelength from that observed in the reflectance spectra of coated polyester fabric; under highpressure P3MT-coated polyester fabric demonstrated piezochromism.
