纳米银复合涂层对空间下行微生物杀菌性能的实验研究

摘要

Microbiologically influenced corosion ( MIC ) in space materials is a serious threat to the health of astronaut and the safety of equipments. Composites coating with different amount of nano siliver were prepared for the sterilization of Sphingomonas paucimobilis. The sterilization ability of the nano⁃silver/fluorine⁃containing polymer composite increased with the increase of nano⁃silver con⁃tent in the composite. The results indicate that the composite coating has excellent sterilization effect.%针对长期空间环境影响下微生物腐蚀的问题，提出纳米银复合含氟高分子涂层抗腐蚀杀菌策略。将不同含量的纳米银引入含氟高分子中得到纳米银复合涂层材料，以具有强烈腐蚀性的少动鞘氨醇单胞菌作为杀菌对象，测试了银纳米复合材料的杀菌性能，证实了复合材料涂层对该菌的杀菌效果，且随着纳米银含量的提高，对空间下行少动鞘氨醇单胞菌的杀菌能力逐渐增强。
