溶液浸泡结合表面涂层制备超疏水-超疏油表面（英文）
|
摘要
超疏水-超疏油材料在防污、防水、防油等领域有广泛的应用前景而引起人们极度关注。本文用全氟辛酸溶液浸泡锌粉制得超疏水-超疏油锌粉,用聚乙烯醇胶将超疏水-超疏油锌粉粘合、固定到玻璃、木头、塑料、不锈钢、纸片、石头表面后可制得超疏水-超疏油表面,水滴、油滴在其表面的接触角均超过150°。锌粉与全氟辛酸反应后生成Zn[CF_3(CF_2)_6COO]_2,氟代长链烷基的低表面能化学组成与微纳米粗糙结构的协调作用使其表现出超疏水、超疏油性能。相关研究有望为超双疏材料的设计、制备及其在自清洁、防水防油及抗污等领域的应用提供借鉴。
Superhydrophobic-superoleophobic materials have received considerable attention due to their wide potential applications in the fields of anti-fouling,water-proof and oil-proof. In this paper,superhydrophobicsuperoleophobic zinc spheres are first prepared by immersing the zinc spheres into the solution of perfluorooctanoic acid,and then the superhydrophobic-superoleophobic surfaces are obtained by pasting the obtained superhydrophobicsuperoleophobic zinc spheres on substrates of glass,wood,plastic,stainless steel,paper and stone. The contact angles of water and oil droplets on these surfaces all exceed 150°. Zinc spheres react with perfluorooctanoic acid to form zinc perfluorooctanoate,and the coordinate effects of micro/nanometer rough structures and chemical composition with low surface energy of the long fluoroalkyl lead to the formation of superhydrophobicity and superoleophobicity.The research may offer a new idea for the design and fabrication of superamphiphobic materials,as well as their application in self-cleaning,waterproof,oil-proof and anti-contamination.
