Abstract A novel, versatile, environment-friendly, and economical method was developed to fabricate functional superhydrophobic surfaces on various substrates, including wood, bamboo, cotton, filter paper, sponge, glass, textile, and copper. This method involves synthesizing a two-component modifier solution consisting of SiO2 nanoparticles combination with poly(methylhydrogen)siloxane (PMHS) modification. The superhydrophobicity of the coated surfaces was created by PMHS combined with SiO2 nanoparticles to construct a rough hierarchical structure on the substrate surface. As a result, all superhydrophobic surfaces were maintained under an indoor environment and relative humidity (RH) of 50% for 30 days. Furthermore, the superhydrophobic surfaces were also maintained at environmental conditions of minus 20℃ for 24 hours. It was also confirmed that these surfaces exhibited excellent self-cleaning, oil/water separation, and elimination of underwater oil properties. The method for fabricating superhydrophobic materials proposed in this study will have great application potential in preparing large-scale superhydrophobic surfaces for use in ancient building protection.

Self Cleaning

Superhydrophobic surfaces have received enormous attention thanking to their potential applications in the areas of anti-icing, anti-contamination, and oil/water separation. Herein, we have successfully prepared superhydrophobic surfaces, which were synthesized by using the polydimethylsiloxane (PDMS) as adhesive and the magnesium palmitate (Mg-P) were evently coated to form roughness on the surfaces of glass, textile, stainless steel mesh, and paper. The as-fabricated superhydrophobic surfaces possessed excellent water-resistance, self-cleaning properties, durability, and robustness. Remarkably, in the actual oil/water separation, the water contact angle and oil collection efficiency of the superhydrophobic mesh were still more than 150° and 91% even after separation over 10 cycles, respectively. Thus, the superhydrophobic coating has applications potential in self-cleaning, anti-contamination, and oil/water separation fields.
