通过多巴胺的同时聚合和N3P3[NH（CH2）（3）Si（OC2H5）（3）]（6）的水解缩合反应，制备了用于棉织物的耐久性阻燃抗菌复合涂料。银纳米粒子也被引入到涂层中的情况下，任何外部还原剂的情况下，通过原位反应的AgNO3与聚多巴胺（PDA）上的儿茶酚部分。利用能谱仪（EDS）、X射线衍射仪（XRD）、X射线光电子能谱仪（XPS）和扫描电镜（SEM）对涂层的形貌和成分进行了分析。通过热重分析和垂直燃烧试验对该材料的热稳定性和燃烧性能进行了表征。改性棉织物具有良好的阻燃性能，对革兰氏阳性菌S.金黄色葡萄球菌和革兰氏阴性菌E.杆菌该改性是持久的，在30次洗涤循环后具有基本上完整的阻燃性和抗微生物性能。(C)2017爱思唯尔B.V.保留所有权利。
Durable flame retardant and antibacterial hybrid coatings were developed for cotton fabrics via simultaneous polymerization of dopamine and hydrolytic condensation of N3P3[NH(CH2)(3)Si(OC2H5)(3)](6). Silver nanoparticles were also introduced to the coatings by in situ reaction of AgNO3 with catechol moieties on polydopamine (PDA) in the absence of any external reducing agents. Energy dispersive spectrometer (EDS), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM) were employed to study the morphology and constitution of the coatings. Thermal stability and combustion behaviors were characterized with thermogravimetric analysis (TGA) and vertical flammability tests. Considerable flame retardancy was obtained for the modified cotton fabrics, which also exhibited decent antibacterial activities (99.99%) against Gram-positive bacteria S. aureus and Gram-negative bacteria E. coli. The modification was durable with largely intact flame retardancy and antimicrobial properties after 30 washing cycles. (C) 2017 Elsevier B.V. All rights reserved.
