“…Recent advancements have led to the development of superhydrophobic surfaces that embody both high water repellency and enhanced durability [7,9,[12][13][14]. To achieve robust superhydrophobicity, it involves structuring surfaces at two distinct scales: nanosacle structure for water repellency and microscale structure for durability [15].…”

In this study, a superhydrophobic coating with excellent mechanical durability, chemical stability, anti-icing property and self-cleaning property was developed based on epoxy resin integrated with modified SiO2 nanoparticles (m-SiO2 NPs). The surface morphology and roughness of the coating were finely controlled by changing the content of m-SiO2 NPs, with optimal hydrophobicity and self-cleaning efficiency observed at the m-SiO2 NPs incorporation of 30 wt.%. Benefitting from the three-dimensional stable micro-nano structure on the coating surface, the coating exhibited durable hydrophobicity upon multiple tape-peeling damages and good resistance to both acidic and alkaline corrosive environments. Furthermore, the SiO2-EP coating showed a prominent anti-icing property which could delay the water freezing time from 96 s to 650 s. This coating underscored its potential for applications in environments prone to ice formation.

“…Researchers at home and abroad have made some progress in the research of superhydrophobic surfaces, and summarized two main strategies for obtaining superhydrophobic surfaces: (1) constructing micro/nano rough structures on low surface energy materials [13]; (2) using low surface energy materials to modify rough structures [14,15]. At present, the common methods used to prepare superhydrophobic surface include sol-gel method [16,17], etching method [18], deposition method [19,20], spray method [21,22], common modi cation method, electro spinning method [23,24], graft polymerization method [25,26], and impregnation method [27,28].…”

Superhydrophobic surfaces have been extensively studied for their self-cleaning properties. However, most of the constructed superhydrophobic surfaces have problems of changing the surface morphology and color of paper/cloth. An extremely dilute superhydrophobic solution was prepared by hybrid assembly of aminated nano SiO 2 and high uorine epoxy polymer P(FOEMA-r-GMA). The preparation of superhydrophobic cotton (SHC) and superhydrophobic book paper (SHBP) were studied through the optimal construction conditions of solution impregnation method. The optimal construction conditions for SHC were as follows: the concentration of uorinated epoxy polymer was 3 mg/mL, the soaking time was 5 hours, the drying time was 8 hours, and the drying temperature was 120 o C. The maximum WCA is 158 ° ± 3 o , and the minimum WRA is 4 o ± 3 o . SHC surface had good hydrophobic effect, acid and alkali resistance, self-cleaning effect, and its surface morphology remains basically unchanged. SHC could be used for oil water separation with a maximum oil water separation rate of 98.4%. The optimal construction conditions for SHBP were: the concentration of uorinated epoxy polymer was 3 mg/mL, the soaking time was 9 hours, the drying time was 6 hours, the maximum WCA was 155 o ± 3 o , and the minimum WRA was 6 o ± 1 o . The hydrophobicity of SHBP was signi cantly improved, it would selective adsorbing oil from the oil water mixture and slightly reduce its smoothness.
