| 中文摘要: |
| 将充分溶胀的壳聚糖与三偏磷酸钠交联并与硅溶胶共混，制备出了壳聚糖复合保鲜膜,用万能拉力机测试了其拉伸性能。研究结果表明，交联和共混明显提高了壳聚糖复合保鲜膜的力学性能，并且壳聚糖浓度在1.2×10-4~1.4×10-4 mol/L，三偏磷酸钠的含量在0.08%，m-SiO-2∶m-壳聚糖约为0.15时，保鲜膜综合力学性能最佳。 |
| 英文摘要: |
| Chitosan films were corsslinked with sodium termetaphosphate and blended with SiO-2, and tested with tension machine. The results showed that the tensile strength of the composite preservative films was considerately improved, and when the concentration of chitosan was 1.2×10-4~1.4×10-4 mol/L, the sodium trimetaphosphate content was 0.08% and m-SiO-2∶m-chitosan was 0.15, the film's comprehensive mechanical properties is the best. |
