超疏水涂层及其功能化研究进展

Research Progress of Superhydrophobic Coatings and Its Functionalization

作为特种涂层,超疏水涂层的研究和应用一直备受关注。近年来,在超疏水的基础上,进一步赋予涂层功能以满足新兴领域的需求成为当前的研究热点。文中介绍了超疏水涂层的制备方法,包括模板法、相分离法、溶胶凝胶法、层层组装法和喷涂法,并对比了其优缺点。综述了超疏水涂层功能化(导电性、阻燃性、导热性、透明性和自修复性)的研究进展,并指出其在实际应用中的重要性。最后总结了目前超疏水涂层领域存在的问题,并对其未来的发展方向进行了展望。

As special coating,the research and application of superhydrophobic coating have always been paid considerable attention to.In recent years,based on superhydrophobicity,endowing the coating with function to meet the requirements of emerging fields has become current research hotspot.In this paper,the main preparation methods of superhydrophobic coating were introduced,including template method,phase separation method,sol-gel method,layer by layer assembly method and spraying method,and their advantages and disadvantages were compared.Then,the research progress of the functionalization(electrical conductivity,flame retardancy,thermal conductivity,transparency and self-healing)of superhydrophobic coatings were reviewed in detail,and the importance in practical application was pointed out.Finally,the existing problems in this field were summarized,and the development directions in future were looked forward.
