摘　　要：研究了硫化银量子点复合纳米二氧化钛对织物自清洁功能的提升作用。试验以硝酸银为银源,巯基乙酸为配体,合成水溶性硫化银量子点,并在pH值2、钛酸四丁酯和水的物质的量比1∶200、陈化时间24 h的条件下制备纳米二氧化钛溶胶。采用二氧化钛溶胶复合硫化银量子点对布样进行处理,并测定处理后布样的自清洁能力,得到优化的处理条件为:硫化银浓度0.5 mmol/L、pH值8、温度25℃。The improvement of self-cleaning performance of cotton fabric treated with Ag2S quantum dots and nano-TiO,is studied.The water-soluble Ag2S quantum dots are synthesized using AgNO3 as silver source and TGA as ligand.Nano-TiO2 sol is prepared under the condition of pH value 2,mole ratio of tetrabutyl titanate to water 1:200,and aging time 24h.The samples are treated by Nano-TiO2 and Ag2S quantum dots,and the self-cleaning performance of treated samples is tested.The result shows that the optimal treatment process is:pH value 8,temperature 25℃,AgeS concentration 0.5mmol/L.
