| Abstract: | CCMC/PVA blend film was prepared by solution mixing method.The effect of glutaric dialdehyde crosslinking agent on the hydrolytic resistance,light transmission and mechanical property of CCMC/ PVA complex film were studied.The results showed that the compactness,water resisting property and mechanical property of CCMC/PVA blend film increased remarkably by crosslinking treatment.The tensile strength was 18.91 MPa,elongation at break was 226%,luminousness was 75% when the amount of glutaric dialdehyde was 2%,pH was 10,crosslinking reaction temperature was 85 ℃,and reaction time was 35 min respectively. |
