In this research, radiation crosslinking of poly(ε-caprolactone) (PCL) films containing various crosslinking agents (CAs) was studied. The PCL films containing different CAs were crosslinked using electron beam irradiation at various absorbed doses and the crosslinked PCL films were then investigated in terms of their crosslinking degree, thermal and mechanical properties, and biodegradability. Based on the results of the crosslinkiing degree measurement, the triallyl isocyanurate at a concentration of 3 wt% was found to be optimal for the radiation crosslinking of PCL. The thermal and mechanical properties of the crosslinked PCL films were improved, while their biodegradability was reduced. |
