Tribological Study of Biocompatible Hybrid Organic Molecules Film with Antibacterial Effect
Journal Title: Tribology in Industry - Year 2013, Vol 35, Issue 2
Abstract
Optical glass is widely used in bioengineering and various utilities such as public touchscreen displays and mobile devices. This work evaluates the features of anti‐bacterial and anti‐adhesion on Octadecyltrichlorosilane (OTS) material that was mixed with a biocompatible antibacterial agent coated on the optical glass. Test samples were allocated to different bath and drying temperatures as well as reaction times. Results show that in angle contact experiments, pure OTS films and mixed antibacterial films have almostthe same contact angle of about 105° under the conditions of a 12 hour reaction time and 80 °C reaction temperature. The antibacterial test indicated the following order: antibacterial agent> OTS+ antibacterial agent (50 %) > OTS+ antibacterial agent (10 %) > OTS. At the same operation condition, OTS mixed with 50 % antibacterial agent was able to increase the adhesion force between the OTS film and lens. This suggests that surface treatment of optical lenses involving OTS with 50 % antibacterial solution is the most effective for increasing antifouling and antibacterial functions while simultaneously‐enhancing the adhesion function betweenfilms andlenssurfaces.
