TEMPERATURE DEPENDENCE OF CONDUCTIVITYOF UREASEDOPED POLYPYRROLE MATERIAL

In situ polymerization of pyrrole was carried out in the presence of urease tosynthesize polypyrrole–urease composites by chemical oxidation method.ThePPy/ urease have been synthesized with various compositions (10, 15, 20, 25and 30 wt%) of urease in pyrrole in aquas medium at room temperature. Thepolypyrrole– urease composites were characterized by infrared spectroscopy(IR). The d.c. conductivity was studied in the temperature range from 40–100◦C. The dimensions of urease in the matrix have a greater inβluence on theobserved conductivity values.
