摘要
以物理气相沉积的方式,将聚合的笼型半硅氧烷材料(F-POSS)和抗菌剂吡啶硫酮锌沉积到玻璃表面,利用FT-IR、SEM、UV-Vis对其组成、形貌、光学性能进行表征,并通过对大肠杆菌和金黄色葡萄球菌进行细菌计数分析,对样品的抗菌能力进行了评估.结果表明,所制备的涂层表面平整具有基体玻璃90％的透明度与118°的水接触角.涂层拥有优良的耐磨、冲击能力,具有一定自修复能力,并且对酸碱、高温等苛刻条件表现出了极佳的稳定性.同时,对常见的大肠杆菌和金黄色葡萄球菌都能在24 h内达到超过98％的杀菌能力.
Abstract
In this paper,fluorinated polyhedral oligomeric silsesquioxanes(F-POSS)and the antimicrobial agent zinc pyrithione were deposited onto the surface of glasses by physical vapour deposition.FT-IR,SEM,and UV-Vis were used to analyze the composition,morphology,optical properties,and the antimicrobial capacity of the samples.And the antibacterial ability of the samples was evaluated through bacterial count analysis of Esche-richia coli and Staphylococcus aureus.The results show that the prepared coating has a homogeneous surface with 90％transparency and 118° water contact angle.It has excellent abrasion and impact resistance,some self-repairing ability,and shows excellent stability to acid,alkali,high temperature and other harsh conditions.Meanwhile,it can achieve more than 98％bactericidal ability against both common E.coli and Staphylococcus aureus within 24 hours.
