摘要:
为了改善聚乙醇酸（PGA）复合材料在常温下的降解和力学性能，以PGA为原料、脂肪族聚酯（聚酯-A）为填料，通过熔融共混法制备了PGA/聚酯-A复合材料，并分析了聚酯-A质量分数对于复合材料力学性能和降解速率的影响。结果表明：当聚酯-A 质量分数为15%时，复合材料的拉伸应力和断裂伸长率分别达到89.18 MPa和4.21%，相较于PGA分别增加了117.19%和120.42%；复合材料样条降解30 d后质量损失为4.13% ，相较于PGA下降了61.62%；随着聚酯A质量分数的增加，复合材料中PGA组分结晶度先降低后增加，复合材料的拉伸强度先增加后减小、断裂伸长率逐渐增加、降解速率逐渐降低、亲水性增加；在复合材料样条断面观察到“海岛”结构的微观形态，并且随着聚酯A质量分数提高而更加明显地出现两个组分之间的相分离现象。PGA/聚酯-A复合材料可以有效改善PGA在常温下的力学和降解性能，研究可为制备兼具高力学性能和低降解速率的PGA基复合材料提供理论参考。
