可生物降解材料的研究进展

Progress of research on the biodegradable materials

介绍可生物降解材料的研究目的及意义。阐述生物降解材料的降解机理及分类(掺混型、化学合成型、天然高分子型以及微生物合成型材料)。综述影响材料生物降解性的主要因素,包括材料的组成、结构、结晶状态、环境的温度、湿度、pH值以及土壤成分等。指出降解材料当前存在的主要问题,并对其发展前景进行展望。

This essay introduces the research objective and significance of biodegradable materials. It elaborates the biodegradable mechanism, classification of biodegradable materials including blending type degradable materials, chemically composite degradable materials, materials made by natural polymer, microbial synthesis degradable materials. The article also reviews the main factors affecting its biodegradable characteristics, such as the structures and crystallized states of materials, temperature and humidity of environment, pH value around the materials and the component of soils and so on. And the main present problems which are related to the degradable materials are pointed out and the development on biodegradable materials is also in prospect.
