Therefore, the mankind have been stained problem caused by sea organism attachment always and have perplexed since developing and using marine resources.
Marine biofouling is mainly prevented and kill off by physical method at present.Specifically, physical method is usually to use impressed current
Method, i.e. electrolysis heavy metal such as copper, aluminium, electrolytic seawater etc., principle is to be killed, pressed down by ion caused by electrochemical method
Marine growth or chemical ion processed recombine to form certain gluey protective layer, slow down corrosion rate.But current this method
Antifouling capacity and processing capacity it is all limited, while can not carry out quick water process with reach use standard.
