由於船舶減阻通常有兩種，其一是藉由改變外型而達到減少興波阻力，另一即藉由船殼表面之處理來減少摩擦阻力，本文主要研究即以後者為主，擬以蓮花效應之構想，開發出具有高接觸角之奈米塗料，來減低船舶表面之摩擦阻力，並藉以提高其防污能力。
本研究主要是利用含氟的矽烷進行SiO2奈米粉末改質，成為容易被甲苯潤濕之粉末，並利用不同基材架構與氧化亞銅(Cu2O)調製成奈米塗料，進行接觸角、硬度、附著力、鹽水噴霧、生物毒性、漁船船模與翼板阻力、海洋曝露等各種實驗。其中以Silicone為基材的高接觸角奈米塗料，經海洋曝露實驗與迴流水槽沖擊實驗下發現可使海生物附著不易，並且與市面船舶防污面漆經翼板阻力實驗比較下，在中低速航行之船舶，平均可減低阻力達11.5%；經漁船船模阻力實驗比較下，平均可減低阻力達13.8%。

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.
