In situ polymerization of pyrrole was carried out in polymethylmethacrylate solution in ethyl acetate by chemical oxidation to form a composite solution system of soluble polypyrrole polymethylmethacrylate matrix.Using the method of solvent evaporation, Can be prepared with good mechanical properties polypyrrole polymethylmethacrylate matrix composite film.With the four-electrode method for the determination of conductivity, the pyrrole content reaches 30%, the conductivity of the composite film reaches its maximum, up to 3S / m, the film has good stability in the air, and the factors affecting the polymerization reaction (temperature, time, matrix content) were studied.
