Naoki Tagami,M. Okada,Naoshi Hirai,Yoshimichi Ohki,Toshikatsu Tanaka,Takahiro Imai,Miyuki Harada,Mitsukazu Ochi +7 more
TL;DR: In this article, the differences in the curing agent and filler dispersion method on the dielectric properties were examined for epoxy/clay nanocomposites, and the results of UV photon absorption and PL measurement showed that the bandgap or the energy at which the photon absorption increases drastically is smaller in the amine-cured samples than in the acid anhydride-Cured samples.
