中文摘要:
      目的 以聚乳酸 (PLA) 为基材,与壳聚糖 (CTS) 相结合制备抗菌复合材料。方法 通过熔融挤出复合工艺制备全生物降解抗菌复合材料, 考察壳聚糖对复合材料力学性能和抗菌性能的影响。结果 复合材料的拉伸强度和弯曲强度随着壳聚糖质量分数的增加而略有降低的趋势, 其缺口抗冲击强度基本不受壳聚糖的影响, 断裂伸长率则呈现先上升后减小的趋势。当壳聚糖质量分数为4%时, 复合材料具有较佳的综合力学性能。当壳聚糖的质量分数为8%时, 复合材料具有较明显的抗菌能力。结论 全生物降解聚乳酸壳聚糖复合材料具有广阔的应用前景, 尚需要继续深入探讨两者之间的关系,以制备性能更加优良的全生物降解型材料。
英文摘要:
      The aim of this study was to prepare composite antibacterial materials using PLA and chitosan. The biodegradable materials were first prepared by hot-melt extrusion, and then the influence of the percentages of chitosan was researched through the test of mechanical property and antibacterial property. With the increase of the chitosan content, the tensile strength and bending strength of the composite materials showed a slightly decreasing trend, the impact resistance at the fracture was substantially unaffected and the elongation at break showed a downward trend after initial rise. When 4.0% mass fraction of chitosan was added, the composite material had the best comprehensive mechanical property. When 8.0% mass fraction of chitosan was added, the composite material showed obvious antibacterial activity. The biodegradable composite made from polylactic acid and chitosan has broad prospects, we need to further explore the relationship between the two materials to prepare a more excellent biodegradable composite.
