Electron beam-induced crosslinking of polycaprolactone (PCL) films containing variouscrosslinking agents (CAs) was investigated in this study. PCL films containing various CAs preparedby a solution casting method were irradiated by electron beams at various absorption doses andthe irradiated PCL films were investigated in terms of their crosslinking degree, thermal andmechanical properties, and biodegradability. Based on the results of the crosslinking degree measurement,triallyl isocyanurate was found to be most effective for the electron-beam induced crosslinkingof PCL films. The results of the UTM, DMA, and TMA revealed that the thermal andmechanical properties of the crosslinked PCL films were greatly improved in comparison to thoseof the pure PCL. The results of the enzymatic degradation test revealed that the biodegradabilityof the crosslinked PCL films was reduced in comparison to that of the pure PCL.
