nanofilm on glass has been successfully produced via the sol-gel dip-coating technique and modified by a rapid microwave plasma-nitridation process at 1200 W for 1 min. The film properties are simultaneously reaching the high transmittance of film/glass (> 90%), high hardness (8H), and high adhesion (5B). Moreover, the self-cleaning and anti-fogging applications of the film/glass can be easily achieved by visible photo-induced superhydrophilicity and photocatalysis for application within in weak or nonexistent UV light irradiation environments.
