Abstract

In recent years, conductive polymers have been extensively used in Mechatronics industries. They are new generation of smart materials for fabrication of actuators. Conductive polymers is a layered polymer‐metal composite with high technology processing. The objective of this project is production and processing of Polypyrrole ‐ gold ‐ Polyvinylidene fluoride (PVDF) composite. The porous PVDF membranes were first sputtered with gold as a conductive layer. The solution of propylene carbonate, pyrrole and lithium triflouromethane sulfonamide salt employed as electrolyte for electroplating of poly pyrrole on gold layer in controlled condition. The composite layers and the influences of temperature, current and time of electroplating electrolyte concentration and the thickness of gold layer on characteristics of trilayer polymer were investigated with SEM and FTIR analysis. The results indicated that with increase of the thickness of gold layer and electroplating duration the thickness of poly pyrrole layer increases. Meanwhile, the optimum condition of electroplating was obtained in 0.1 molar concentration of pyrrole and lithium tri flouromethane sulfonamide salt temperature of ‐25 °C.
