摘　　要：以风驱动旋转圆盘摩擦纳米发电机(WRD-TENG)为主体,结合太阳能电池,储能锂电池、时控开关成功构建了时间精准操控的自供电电解析氯系统。测试结果表明:尺寸稳定阳极(DSA电极)电解析氯20 min产生的活性氯对铜绿假单胞菌和金黄色葡萄球菌有明显的杀灭效果,杀菌率都达到95%以上。自供电系统的太阳能电池和WRD-TENG可以单独或同时收集能源,并且输出具有互补性,锂电池和时控开关赋予了复合系统储能和时间精准操控的特性,复合体系可以成功驱动电解析氯体系。A wind driven rotating disc friction nano generator(WRD-TENG)as the main body,combining with solar cells,energy storage lithium batteries,and time-controlled switches,and a self powered chlorine analysis system with precise time control was successfully constructed.The test results show that the active chlorine generated by the DSA electrode′s electrochemical analysis of chlorine for 20 minutes had a significant killing effect on pseudomonas aeruginosa and staphylococcus aureus,with all the bactericidal rates over 95%.The solar cells and WRD-TENG of the self-powered system could collect energy separately or simultaneously,and their outputs were complementary.Lithium batteries and time-controlled switches endowed the composite system with energy storage and precise time-control characteristics,and the composite system could successfully drive the electrolytic chlorine evolution system.
