将从植物源色素中分离出的鞣花酸(EA)以不同比例添加于聚丁二酸丁二醇酯(PBS)中,采用POM、WXRD、DSC、TG和力学性能测试,研究了少量EA的添加对PBS晶型结构和性能的影响。研究结果表明:0.5%~2.5%EA的添加,虽然PBS的结晶型态没有改变,但细化了PBS的球晶尺寸,使PBS的结晶度也有所增大;并且EA的添加提高了PBS的结晶温度和热稳定性,加快了PBS的结晶速率;PBS的拉伸强度有所提高,综合力学性能良好。 Ellagic acid (EA) isolated from plant-derived pigments was added to polybutylene succinate (PBS) in various proportions. POM, WXRD, DSC, TG and mechanical properties were used to test the effect of EA The effect of addition on the crystal structure and performance of PBS. The results showed that the addition of 0.5% ~ 2.5% EA did not change the crystal form of PBS, but the spherulite size of PBS was refined and the crystallinity of PBS was also increased. Crystallization temperature and thermal stability, speed up the crystallization rate of PBS; PBS tensile strength has improved, good overall mechanical properties.
