Preparation of Conductive PPy/Cellulose Composite Fabric by Using Admicellar Polymerization
Conductive PPy/cellulose composites were prepared with flax substrate by using admicellar polymerization. In admicellar polymerization, thinner PPy layer would be formed by a surfactant template. The stability of conductive composites prepared under various conditions was analyzed and surface morphology of the composite was analyzed by SEM. The effects of different preparation conditions on the conductivity of the composite were studied in detail. The optimum preparation conditions were as follows: pyrrole concentration 0.3 mol•L-1 , FeCl3 concentration 0.3 mol•L-1, adsorption time 150 min, PVA to pyrrole weight ratio 2%, polymerization temperature 0°C, polymerization time 9h. The surface resistivity of conductive composite fabric almost linearly increased with the prolongation of storage time. The stability of the conductive composite is the best when PVA/ pyrrole is 2%.
