| Research Abstract |
In the present work we report on preparation of composite materials of polypyrrole and electroactive polymer gel using for the two dimensional conveying system in biomimetic engineering. Composite materials of conducting polymer and polymer gel prepared by chemical oxidative polymerization. Poly vinyl alcohol gel and Poly (2-acrylamide-2-methyl propane) sulfonic acid gel were prepared by thawing-melting method and radical polymerization, respectively. Strips of polymer gel were immersed in 1 mol/1 pyrrole solution over night. The surface structures, mechanical properties, and electrical properties of the gels were investigated. It is observed that polypyrrole homogeneously penetrated into cross-linking matrix of conducting polymer gel. This rigid chemical structure of the composite material plays a very important role in affecting the mechanical properties of the soft material. Ratio of water content of composite material is the same as that of polymer gel, on the other hand, the mechanical strength, and conductivity of composite material remarkably improved.
The gels were stimulated by the application of various electric fields. Cylinders of conducting electroactive polymer gel, usually about 5mm in diameter and 10 mm long, were stimulated at a range of V/cm values between carbon electrodes in 50mM Na_2SO_4 solution. The elasticity of composite materials was significantly increased with ratio of polypyrrole in the gel. The bending rate of the polymer gel under the electric fields was increased with the ratio of polypyrrole in the composite material and the magnitude of applied voltages. We also succeeded to demonstrate that many cylinders of this conducting electroactive polymer gel embedded in water solution bent uniformly toward the electrode by the application of various electric fields.
