摘要
结冰对人类的日常生活和工业应用造成巨大的危害,而超疏水表面因其不消耗外部能量即能有效地用于防除冰而受到人们的特别关注;提出一种使用乙醇辅助飞秒激光制备三维多孔超疏水表面的方法,并研究其在不同激光加工参数下的性能.制备的三维多孔结构可以将照射在超薄镍箔表面的太阳光有效吸收,其太阳照射饱和温度是裸镍表面的1.36倍,可有效地提高光热除冰效率.此外,该结构在材料表面会形成一层稳定的气膜,使其具有优异的超疏水性能.这种简单快速的三维多孔超疏水表面制备方法,将在防除冰、光电子、物理和化学等领域展现广阔的应用前景.
Abstract
Icing has caused great harm to human daily life and industrial applications,and superhydrophobic surfaces have at-tracted special attention because they can be effectively used for anti-icing without consuming external energy.In this paper,we present a method to fabricate three-dimensional porous superhydrophobic surfaces using ethanol-assisted femtosecond laser,and investigate its performance under different laser processing parameters.The prepared three-dimensional porous structure can effectively absorb the sunlight irradiated on the surface of the ultra-thin nickel foil,and its solar irradiation saturation tempera-ture is 1.36 times that of the bare nickel surface,which can effectively improve the photothermal deicing efficiency.In addi-tion,this structure will form a stable gas film on the surface of the material,making it have excellent superhydrophobic proper-ties.This simple and rapid preparation method of three-dimensional porous superhydrophobic surface will show broad applica-tion prospects in the fields of anti-icing,optoelectronics,physics and chemistry.
