Composite coating to control biofilm formation and effect of alternate electro-magnetic field

Abstract

Three kinds of composite coating (the common matrix was silane oligomer and titanium organic, tin organic and nickel organic compounds were dispersed in the matrices) specimens on glasses were immersed in a unique Laboratory Biofilm Reacter (LBR) for 12 days. In the LBR, the water was circulated, incorporating ambient germs into the system and biofilm was formed on the specimen set in the LBR. In the LBR, clean water was circulated and the weak alternative electromagnetic field was applied to the water phase. For the biofilm resistant coating (organic titanium or tin composite coating based on silane oligomer), the effect of the applied alternative electromagnetic field was remarkable.
