The influence of temperature on polypyrrole coated cotton fabric

Popis výsledku v původním jazyce

Original abstract In this study, polypyrrole (PPy) was coated by chemical oxidation through in-situ polymerization technique. Tetraethyl ammonium p-toluene sulfonate (TEAp-TS) was chosen as doping agent along with FeCl3 as oxidizing agent. Six differentfabric samples were prepared by varying concentration of monomer, doping agent and oxidizing agent in order to achieve different samples with electrical conductivities. Each sample was exposed to four different temperatures (80, 120, 160 and 200 °C) andelectrical resistivity was recorded at different intervals in the range 0-600 sec. In this way the influence of temperature on electrical resistivity of PPy coated fabric samples was analyzed and found that resistivity decreases with the increase in temperature. IR spectrum confirms that there is no change in PPy before and after heating of samples. SEM micrographs showed the deposition of PPy on cotton fibers surface.
