Abstract
Slippery Liquid-Infused Porous Surface (SLIPS) has been shown promising potentials in the field of metal corrosion protection. However, the complicated strategy curbs its forward application. In this work, epoxy resin (ER) coating with surface texture was prepared by soft lithography, and the ER-based SLIPS was easily obtained through subsequent modification treatment and lubricating oil injection process. SEM images revealed that the micromorphology of sandpaper was perfectly replicated to ER coating surface. Due to the mineral oil film locked by surface texture with fluorinated layer, the wettability test demonstrated that ER-based SLIPS had excellent hydrophobic property and low sliding angle with 3.5°. Benefiting from the low surface energy characteristic of oil film and its barrier effect to corrosive media, the ER-based SLIPS exhibited fascinating anti-corrosion performance. All these properties indicated the great possibilities of future applications of the ER-based SLIPS in the field of corrosion protection.
