| 中文摘要: |
| 采用 NMMO 溶解工艺,制备了可完全降解的纤维素膜,研究了凝固浴温度对纤维素膜机械强度、溶胀性、抗菌剂保留率、抑菌性能的影响。 结果表明:随着凝固浴温度的升高,纤维素膜的拉伸强度、断裂伸长率下降,且导致纤维素膜在不同食品模拟液中的溶胀度改变;同时凝固浴温度的改变,纤维素膜中百里酚的含量显著降低,从而抑菌效果也相应降低。 |
| 英文摘要: |
| Fully degradable cellulose film was prepared by NMMO progress. The influence of coagulation bath temperature on mechanical strength, swelling property, antibacterial agent retention rate, and antibacterial properties was studied. The results showed that with the increase of coagulation bath temperature, the tensile strength of the cellulose film and the elongation at break has a certain reduction; the swelling properties in different food simulants change; the change of coagulation bath temperature can cause huge decrease of the retention rate of thymol in the film, so that the inhibitory effect is reduced accordingly. |
