碩士 / 國立成功大學 / 系統及船舶機電工程學系碩博士班 / 94 / There are two kinds of ship resistance. One is that changing the appearance would result in the decrease of wave-making resistance. Another is to change the coating surface of the ship resulting in a decrease of friction resistance. Our research is to investigate the latter. The idea of the lotus-effect leads to the development of a high contact angle of nano coating which reduces friction resistance on the surface of the ship and elevates the surface to prevent pollution.
In the present study, we mainly used silane containing fluorine elements to change the quality of SiO2 nano powder which was wetted by toluene. Furthermore, using different structure of based materials was formulated with oxidize copper (Cu2O) to form the nano coating which was performed on the experiments of hardness, adhesive force, contact angle, salt solution spraying, biological toxicity, ship mould resistance and exposure to ocean, etc. On the other hand, ship at mid low rate(or speed) would reduce by average a resistance of 11.5% through the experiment of resistance of foil. Again, it would reduce the resistance by 13.8% through experiment of fishing boat block mould.
