チタン膜を用いた海生生物付着防止装置

抄録

 The new anti-biofouling system, which utilizes titanium film to prevent the deposition of marine life on various surfaces of the sea equipment, can keep its superior antifouling effect for extended periods of time eliminating the need for repainting of antifouling paint as well as decreasing marine life fouling which is treated as industrial waste. This system has a catalyzed surface on the titanium film acting as an electrode connected to an external electric power supply. The active oxygen generated on the electrode surface oxidizes and degrades organic matters in seawater electrochemically when they make contact with the catalyzed surface. Since organic matters are nutrients for bacteria, bacterial growth and the subsequent slime formation can be inhibited. Thus, the consequent attachment of seaweedsand the fouling of larger marine organisms can be prevented.
