| 中文摘要: |
| 采用流延成膜工艺制备了CCMC/PVA共混复合膜，研究了戊二醛交联剂对复合膜的透光性能和力学性能的影响。结果表明：交联处理膜的致密性和机械性能显著提高；当戊二醛添加量为2%(质量分数)，体系的pH为10，交联反应温度为85 ℃，交联时间为35 min时，复合膜的拉伸强度可达18.91 MPa，断裂伸长率为226%，透光率为75%。 |
| 英文摘要: |
| 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. |
