Comparison of gamma-ray resistance between dicyclopentadiene resin and epoxy resin

Radiation resistance was compared between dicyclopentadiene (DCP) resin (P) and epoxy resin (E) by analyzing mainly their complex permittivity ( ε r ' and ε r ") and electrical conductivity. While both ε r ' and ε r " increase significantly in E with an increase in total dose of...

Description
Summary:Radiation resistance was compared between dicyclopentadiene (DCP) resin (P) and epoxy resin (E) by analyzing mainly their complex permittivity ( ε r ' and ε r ") and electrical conductivity. While both ε r ' and ε r " increase significantly in E with an increase in total dose of the gamma irradiation, no such increases are observed in P. The conductivity is always smaller in P than in E and the difference becomes larger with the increase in total dose. This difference becomes very obvious if we pay attention to electric modulus spectra. These results indicate clearly that P has a better gamma resistance than E.
