Abstract
Enzyme doped polypyrrole polymer were synthesized by in situ polymerization where ferric chloride works as an oxidizing agent. The different weight percent of papain was added at the time of polymerization. The polypyrrole-papain composite of various composition was analyzed for its dielectric and a. c. conductivity by using LCR meter at room temperature. Dielectric constant and loss decreases, with escalation in frequency. The variation in dielectric constant and dielectric loss was also noted with change in papain percentage in pyrrole.

The AC conductivity and Dielectrical property for polypyrrole-papain composite were analyzed for variation of frequency, which ranges from 100 Hz to 1MHZ by using HP-LCR Meter (HIOKI3532-50 hi tester)
Summary
Intrinsic conducting polymers have fascinated the people as advanced materials, because of its electrical and optical properties which are generally seen in inorganic materials. The difference in conducting polymers and inorganics materials is that the conducting polymers are molecule in nature and have long range order [1]. Out of many conducting polymers available polypyrrole, poly aniline, and many more polymers like polypyrrole composites are more promising for various marketable applications because of its environmental stability and higher conductivity. Polypyrrole have an exceptional thermal stability so there carbon composits are used for coating [7]. Polypyrrole and composite polymer can be used as drugs delivery and bio-molecules [8], polypyrrole polymer blends can guard the metals from corrosion [9]. The papain enzyme has high optimal temperature up to 65 0C and a varied pH range from 5-8 for its activity. Http://www.granthaalayah.com ©International Journal of Research - GRANTHAALAYAH [332]
