| 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. |
