Alternating Current Conductivity of Papain Doped Palypyrrole Composite Polymer

Abstract

The present study discusses about alternating Current conductivity of Papain doped polypyrrole composite polymer. Enzyme papain doped pyrrole 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, at room temperature. The LCR meter was used for investigate of the dielectric and a. c. conductivity of the polypyrrole-papain composite of different compositions. Dielectric constant and loss calculations for pure and papain composite polymers get smaller as frequency increases. The variation in dielectric constant and dielectric loss and transportation method was also noted with change in papain percentage in pyrrole. For AC conductivity ’s’ value confirms presence of multi-relaxation time with understanding charge transportation method by hopping between localized state. Further investigation is required to understand process in detail.
