Abstract
Superhydrophobic surfaces have demonstrated significant potential in various fields. Nonetheless, creating durable superhydrophobic surfaces with practical application value remains a major challenge. This study utilizes biomimicry to prepare a series of composites similar to shark skin, which possesses hydrophobic and wear-resistant properties. A dual-coating strategy was developed to create a durable and wear-resistant superhydrophobic surface. This article introduces a novel approach by incorporating chemically modified sepiolite and graphite nanoparticles in a layer-by-layer composite for enhancing wear resistance in epoxy resin coatings. Epoxy resin (EP) was used as the matrix material, graphite nanoparticles (GNP) were incorporated for the wear-resistant layer, and modified superhydrophobic Sepiolite (osSep) particles were utilized for the superhydrophobic layer. Both of these layers could form hydrogen bonds with epoxy resin, leading to a functional coating that offers wear resistance, superhydrophobicity, chemical stability, and self-cleaning properties. This article applies EP@GNP@osSep composites to glass, wood, and stainless steel mesh, imparting excellent superhydrophobic properties, wear resistance, self-cleaning abilities, and anti-staining properties. The superhydrophobic coating prepared in this manuscript can meet the requirements of robustness and superhydrophobicity for various materials, with promising market potential.
