Fabrication and characterization of bionic amphiphobic functional surface on X70 pipeline steel

Technical Paper

Abstract

The amphiphobic surface has extremely broad application prospects in industrial production and daily life, such as preventing the adhering and fouling of materials and prolonging service life. In order to prepare an amphiphobic surface on X70 pipeline steel, a simple method was presented. The rough surface was created by shot blasting and chemical etching, consisting of micro-nano composite structures. The surface was then chemically modified by a low surface energy material, which contains a fluorocarbon group. The surface morphology, roughness, chemical composition, and wettability with distilled water and peanut oil were studied by field emission scanning electron microscopy, confocal microscopy, energy dispersive spectrometer, and contact angle measurement instruments. The results indicated that a micro-nano composite structure was created on the steel surface after shot blasting and chemical etching. The amphiphilic surface with micro-nano structure turned into an oleophobic and superhydrophobic surface after being chemically modified by low surface energy material. The maximum contact angles of the amphiphobic surface with distilled water and peanut oil were up to 150 ± 1° and 140 ± 1°, respectively.
