超疏水自清洁涂层的研究进展

Progress in Superhydrophobic Self- cleaning Coatings

建筑外墙和玻璃常常因为外界粉尘、污水等附着而影响其美观及缩短使用寿命,受"荷叶效应"的启发,并基于表面形貌和化学组成的协同效应,人们制备出了超疏水自清洁涂层将有望解决上述难题。本文重点综述近几年超疏水自清洁涂层的研究进展:从超疏水涂层到超疏油涂层,再到超疏油-超亲水涂层。最后,对超疏水自清洁涂层的未来研究进行了展望。

Building walls and glasses easily adhere to external contaminant, such as dust, sewage, and so on, which extremely affect their appearance and shorten their working life. Inspired from ＂lotus affect＂, a variety of superhydrophobic self - cleaning coatings have been fabricated based on surface morphololgy and chemical compositions, hopefully solving the above - mentioned problems. In this paper, we mianly review the development of superhydrophobic self - cleaning coatings in recent years ： from superhydrophobic coatings to superoleophobic coatings, and to superoelophobic - superhydrophilic coatings. In the end, the promising researches of superhydrophobic self - cleaning coatings in the future are presented.
