摘要
以聚丙交酯为代表讨论了可生物降解聚酯类纤维的结构特征与生物降解性能,对聚酯类纤维生物降解的机理、影响因素进行分析,指出聚合物的分子质量及分子链结构、聚集态结构、环境的温度、湿度、pH值及酶种类等因素对其降解性能有明显的影响,合理控制这些因素,可对其降解速度实现人为控制,以适应不同用途的需要.
The biodegradable properties and their relationships with the structure of polylactide, representative of biodegradable aliphatic polyesters , are discussed in this paper. The biodegradable properties of polylactide are related to its molecular weightB, the chain structure, collective structure, temperature, humidity, pH value and the type of enzymes. If the above factors are put under control, we will be able to control the biodegradable rate, and then can make products for different end-uses.
