Preparation and properties of F-POSS transparent hydrophobic antimicrobial surfaces
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.
