超疏水材料在水管内壁减阻的应用

针对超疏水表面功能材料在流动减阻方面的潜在应用，并结合水利与环境方面的专业知识，以节约能源提高效率为目的，展开了关于超疏水管道的有关研究．通过实验研究疏水材料应用于输水管道的减阻效果，并与普通接触角的超疏水管道对比，得出接触角与减阻效果的图表，继而提出应用于实际的方案．通过实验研究，发现随着接触角增大输水管道内水的流速也有增大趋势．也简要综述了前期的超疏水材料制备和生物应用方面的研究工作．

The Application of Drag Reduction of Super Hydrophobic Materials in the Pipe Wall

This paper carries on a study of super hydropnobic pipes in the light of the potential application ofsuper hydrophobic surface functional material in drag reduction, integrated with the knowledge of water conservancy and environment, with energy saving and efficiency improving as aim. Through experiments to study thedrag reduction effect hydrophobic materials used in conduit and to compare with super hydrophobic pipes of thecommon contact angle, it gains the chart of contact angle and drag reduction efficiency, and then raises thescheme of practical use. The experimental study shows that the flow velocity of the water in the pipe increaseswith the increase of contact angle. At last, this paper also briefly reviews the preparation of super hydrophobicmaterials at the initial stage and the application to biologic studies.
