Influence of gamma irradiation on the electrical conductivity and dielectric properties of polypyrrole conducting polymer composite films
(Universiti Malaysia Perlis (UniMAP), 2019-10)
Electrical conductivity and dielectric properties of polypyrrole conducting polymer
composite films were investigated using gamma irradiation from 0 kGy up to 25 kGy. The
AC conductivity is directly proportional to the ...
