摘　　要：采用天然植物源石榴皮色素添加在可生物降解聚丁二酸丁二醇酯(PBS)中,以取代对环境有害的化学色素,制备了PBS/石榴皮色素复合材料,研究了复合材料的热稳定性、抗菌性、亲水性和生物降解性能。研究结果表明:复合材料的综合性能较纯PBS有很大的提高。当复合材料中色素质量分数为9%时,复合材料表现出明显的抗菌性,其对金黄色葡萄球菌和大肠杆菌的抗菌率分别达到99.18%和99.62%,亲水性提高了16.36%,生物降解性能提高了166.28%,复合材料的热稳定性能也有很大提高。Adding natural punica granatum L. pigments into biodegradable poly （butylene succinate） （PBS） to replace the environmentally harmful chemical substances,the PBS/natural punica granatum L. pigments composites were prepared. The thermal stability,antibacterial ability and hydrophilicity of the composite were tested. The results showed that the properties of the composites were greatly improved. When the content of pigments was 9 % ,the composite had obvious antibacterial ability, and its antimicrobial ratio to staphylococcus cereus and escherichia coli was respectively 99. 18 % and 99.62 % , and the hydrophilicity and degradation of the composites were increased by 16.36 % and 166.28 % respectively. The thermal stability of the composite was obviously improved.
