| 为探索新型可降解膜材料的制备方法及其性能，以柳橙皮为成膜基材，海藻酸钠和羧甲基纤维素钠为增稠剂，甘油为增塑剂，采用流延法制备柳橙皮膜，并探究了柳橙皮浓度、增稠剂浓度、增塑剂浓度对膜力学性能和阻隔性能的影响。结果表明：柳橙皮浓度为1.5%，海藻酸钠浓度为0.1%，羧甲基纤维素钠浓度为0.2%，甘油浓度为0.2%，此时膜的综合性能最佳。其主要指标：抗拉强度为24.08 MPa，断裂伸长率为15.73%，水蒸气透过系数为1.686×10-12 g·cm·cm-2·s-1·Pa-1。研究表明，柳橙皮成膜性较好，且具有良好的力学性能和阻隔性能，是一种具有开发潜力的新型包装材料。 |
| 英文摘要: |
| To assess the preparation and performance of the a new biodegradable film, tape casting was applied to prepare a citrus pericarp based film using sodium alginate and carboxymethyl cellulose as a thickening agent, and glycerin as a plasticizer. The influence of different concentrations of citrus pericarp, thickening agent, and plasticizer on the mechanical and barrier properties of the film were investigated. As a result, each index was present well while citrus pericarp mass concentration was 1.5%, sodium alginate mass concentration was 0.1%, carboxymethyl cellulose mass concentration was 0.2% and glycerin mass concentration was 0.2%. At this composition,the tensile strength was 24.08 MPa, the elongation of the film at the breaking point was 15.73%, and the water vapor permeability was 1.686×10-12 g·cm·cm-2·s-1·Pa-1. In conclusion, the citrus pericarp is shown to be a good base for a biodegradable film.It produces a film with good mechanical and barrier properties and has promising potential for the production of new packaging materials. |
