In recent years, it widely used in many fields such as optics, electronics, biomedical applications. The study of this work is using of biocompatibility antibacterial materials mixed with self-assembled monolayers grown on the optical lens. Study self-assembled film on the optical lens case organization, the transmittance, surface cleanliness and closeness water effects. The experiments in this study prepared five kinds of SAMs, ODS, OTS, Anti50%, ODS+Anti50%, OTS+Anti50%, and divided by the plasma-treated and untreated groups, to do the critical load experiments, adhesion experiments, contact angle experiments. These result indicated that the MgF2 coating can effectively reduce the refraction of light, increasing light ransmission rate from 93% to 97%. The result of experiment showed that in the contact angle of five self-assembled monolayers, the best contact angle of ODS was 117° after 12 hours at 60℃, and the contact angles of OTS, OTS+Anti50%, ODS+Anti50%, and 50% pure antibacterial solution, and control were 104°, 96°, 95°, and 61° respectively. By the enhanced treatment on the interfaces of lenses and SAMs, the result showed critical load of ODS and the ODS with 50% antibacterial solution could raise to 51.1% and 54.46%. By the X-ray photoelectron spectroscopy(XPS) experiments can be learned the self-assembled film has anti-bacterial agents solvent of ethanol and oxygen ions in the bond and the formation of film on the substrate surface, the results show that self-assembled film on the substrate composition film well. And by the long time of 2.5 months experiment and then to measure the contact angle, the enhanced plasma treatment to make the interface of the lens can be found the self-assembled films presence to 2.5 months on the lens. The data suggested, the surface treatment of optical lenses involving ODS with 50% antibacterial solution is the most capable of effectively increasing antifouling and antibacterial functions, and it also inhance the adhesion between films and lense surfaces.
