가교방법이 PVA 필름의 겔 특성에 미치는 영향

초록
Poly(vinyl alcohol) was crosslinked by UV irradiation in the presence of water soluble photoinitiators. The crosslinking of PVA films with 1,2,3,4-Butanetetracarboxylic acid(BTCA) and sodium phosphinate monohydrate(SPM) was also achieved via thermal curing. Different factors in the crosslinking including thermal and radiation methods were studied. Gel fraction of PVA films increased with increasing photoinitiator concentration. The maximum gel fraction on the crosslinking method was reached about 81%. The glass transition and maximum decomposition temperature improved by both thermal and radiation crosslinking.
