| 中文摘要: |
| 输电线路覆冰严重威胁着电力系统的安全运行，各种防覆冰技术的研究开发是对输电线路正常运行的有力保障。防覆冰涂层能够主动抑制和缓解输电线路覆冰的形成和增长，尤其超疏水涂层可延迟水滴在涂层表面的冻结，从而实现防覆冰，具有广阔的应用前景。探讨了表面状态与覆冰现象以及覆冰粘结强度之间的关系，指出超疏水涂层的覆冰状态与普通表面具有较大差别，覆冰粘结强度明显低于普通表面。超疏水涂层实现防覆冰功能的影响因素包括表面化学成分、表面结构与环境因素，而通过简单工艺构建有效超疏水表面是超疏水涂层推广应用的关键。基于对超疏水表面防覆冰机理的分析，可知超疏水涂层具有巨大的防覆冰功能潜能，通过控制组织结构使其适应各种温度等环境因素是目前亟需解决的问题。 |

| Icing on transmission line is severely threatening safe operation of power system, development and research of anti-icing techniques provides strong guarantee for normal operation of transmission line. Anti-icing coating could inhibit or relieve formation and development of icing on transmission line initiatively, superhydrophobic coating has wide application prospect as it can realize anti-icing by delaying drop freezing. The relationship among surface state, icing and ice-adhesion strength was discussed. It was pointed that there was obvious difference between icing state of superhydrophobic surface and that of common surfaces. The ice-adhesion strength of the superhydrophobic surface was also lower. The anti-icing function of the superhydrophobic coating is determined by factors including chemical composition, surface structure and environment, and constructing effective superhydrophobic surface in simple preparation process is crucial to popularizing and applying the superhydrophobic coating. Based on anti-icing mechanism analysis for superhydrophobic surface, it can be concluded that there is great potential for superhydrophobic coating, it is in urgent to adapt the coating to environmental factors including various temperature by controlling its structure. |
