【摘要】 高分子的生物腐蚀影响其在多种工业材料的应用,包括航空航天结构复合材料、高分子增塑剂和添加物、电绝缘聚酰亚胺、腐蚀防护高分子外衣。高分子物质微生物腐蚀的作用机理是:合成高分子材料能否成为抑氧微生物的底物主要取决于其化学结构、结合性能、微生物群落。生物腐蚀的程度还取决于聚合物的摩尔质量、结晶度、物理形态。更多还原

【Abstract】 Biodeterioration of polymers affected its application in a wide range of industries included aerospace structural composites,polymeric plasticizers and additives,electrical insulation polyimide,corrosion resistance polymeric covering.The mechanisms of microbiological deterioration of polymeric materials was synthetic polymers could be potential substrates for heterotrophic microorganisms,depending on chemical structures,combination performance,and microbial community.The degree of deterioration also depended on molecular weight,crystallinity,and the physical form of the polymer.更多还原
