摘　　要：采用无皂乳液聚合方法,以甲基丙烯酸甲酯(MMA)、苯乙烯(St)和丙烯酰氧乙基三甲基氯化铵(DAC),合成不同粒径的P(St-MMA-DAC)聚合物微球,通过雾化沉积法在涤纶织物上制备结构色。对P(St-MMA-DAC)聚合物微球及结构色织物进行了红外光谱、扫描电镜、粒径、反射光谱和抗菌性能测试。结果表明,通过改变合成过程中单体比例可以得到不同粒径的P(St-MMA-DAC)聚合物微球,可在涤纶织物上形成蓝色、粉红色、绿色、青色和紫色5种不同颜色的结构色。结构色织物对大肠杆菌(E.coli)和金黄色葡萄球菌(S.aureus)的抑菌率可达到98%以上,表现出优异的抗菌性能。本文为功能性聚合物微球开发及在纺织、医疗卫生等领域的应用提供了研究基础。P(St-MMA-DAC)polymer microspheres with different particle sizes were synthesized by soap free emulsion polymerization using methyl methacrylate(MMA),styrene(St)and acryloxyethyl trimethylammonium chloride(DAC).The structural colors were formed on polyester fabric by atomization deposition of these P(St-MMA-DAC)polymer microspheres.Infrared spectroscopy,scanning electron microscopy,particle size,reflectance spectroscopy,and antibacterial performance tests were conducted on P(St-MMA-DAC)polymer microspheres and structural color fabrics.The results indicate that P(St-MMA-DAC)polymer microspheres with different particle sizes can be obtained by changing the monomer ratios during the synthesis process,which can form five different structural colors of blue,pink,green,cyan,and purple on polyester fabrics.The antibacterial rates of structural color fabrics against Escherichia coli(E.coli)and Staphylococcus aureus(S.aureus)can reach over 98%,showing excellent antibacterial properties.This study provides a research basis for the development of functional polymer microspheres and their application in textile,medical and health fields.
