제목 Activation energy and decomposition behavior of ETFE-g-PVBC films by thermogravimetric analysis
초록 In this study, various poly(vinylbenzyl chloride)-grafted poly(ethylene-co-tetrafluoroethylene) [ETFE-g-PVBC] films that can be used as precursors for ion-exchange membranes were prepared with a radiation grafting technique and the effect of degree of grafting on the thermal decomposition behavior of ETFE-g-PVBC films was evaluated. The DSC results revealed that the crystalline domain contents of ETFE-g-PVBC films were reduced with increasing degree of grafting. The DMA results observed that the initiate crosslinking reaction of the PVBC grafted film occurs at over 250 oC. The thermal properties of grafted films were found that the decomposition temperature was increased with increasing degree of grafting. The Ea values for the thermal decomposition of three different DTG peaks of the ETFE-g-PVBC films were increasing with increase in degree of grafting. These results indicate that the crosslinking reaction of ETFE-g-PVBC films was increased with increasing degree of grafting.
