Abstract

Structural color is expected to replace traditional chemical color due to its advantages of brilliant colors, environmental friendliness and fading resistance. At present, the research of structural color mainly focuses on color saturation and color fastness. Structural colors with specific functions are urgently needed to expand their applications. In this study, poly (methyl methacrylate/tert-butyl acrylate/[3-(methyl acrylamide) propyl] trimethyl ammonium chloride) (P (MMA/t-BA/MAPTMA)) microspheres containing antibacterial quaternary ammonium salt monomer were synthesized by soap-free emulsion polymerization method. The structural color was prepared on the black polyester fabric by atomization deposition, and then sprayed polydimethylsiloxane (PDMS) to prepare structural color fabrics with antibacterial and superhydrophobic properties. By changing the molar ratio of the monomer, five kinds of P (MMA/t-BA/MAPTMA) microspheres with different particle sizes can be obtained, so as to obtain different structural colors of blue, purple, green, cyan and red on the polyester fabric. The inhibition rates of structural color fabric against E. coli and S. aureus are over 99 % showing excellent antibacterial properties. The water contact angles of structural color fabric after PDMS treatment can reach greater than 150° showing excellent superhydrophobicity. And the superhydrophobic structural color fabric had self-cleaning function. This study provides a new approach and strategy for the development of functional structural color textiles.

制备具有优异抗菌和超疏水功能的结构色织物

结构色因其色彩艳丽、环保、耐褪色等优点，有望取代传统的化学色。目前，结构色的研究主要集中在色彩饱和度和色牢度方面。要扩大结构色的应用范围，迫切需要具有特定功能的结构色。本研究采用无皂乳液聚合法合成了含有抗菌季铵盐单体的聚（甲基丙烯酸甲酯/丙烯酸叔丁酯/[3-（甲基丙烯酰胺）丙基]三甲基氯化铵）（P（MMA/t-BA/MAPTMA））微球。通过雾化沉积法在黑色涤纶织物上制备结构色，然后喷涂聚二甲基硅氧烷（PDMS），制备出具有抗菌和超疏水性能的结构色织物。通过改变单体的摩尔比，可得到五种不同粒径的 P（MMA/t-BA/MAPTMA）微球，从而在涤纶织物上获得蓝、紫、绿、青、红等不同的结构色。结构色织物对大肠杆菌和金黄色葡萄球菌的抑菌率超过 99%，显示出优异的抗菌性能。经 PDMS 处理后的彩色结构织物的水接触角大于 150°，显示出优异的超疏水性能。超疏水结构色织物还具有自清洁功能。这项研究为功能性彩色结构纺织品的开发提供了一种新的方法和策略。

期刊介绍： Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials. OPTICAL MATERIALS focuses on: • Optical Properties of Material Systems; • The Materials Aspects of Optical Phenomena; • The Materials Aspects of Devices and Applications. Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
