The advanced treatment and resource utilization of oily wastewater are of great significance to solve water shortages and realize carbon peaking and carbon neutrality goals. The construction of biomass-based superwetting surfaces with recyclability, non-toxicity, and degradability is considered to be a promising strategy to overcome the unavoidable bottlenecks of "secondary pollution" and high costs in the current design of superhydrophobic structures. In this work, a strategy for preparing multifunctional sodium alginate (SA) superhydrophobic surfaces was proposed. By virtue of the synergistic mechanism of SA, SiO2 nanoparticles, pseudo-polyrotaxane and methyltrimethoxysilane, a superhydrophobic sponge with a green biomass-based carrier was prepared, which was constructed using a superhydrophobic elastomer with a three-dimensional network. The modified SA aerogel has a contact angle of 155.2° and even exhibits strong corrosion resistance in harsh environments with a water contact angle greater than 155°. Notably, the increase of green biomass-based materials provides a promising and sustainable development path for the preparation of hydrophobic substrates. [ABSTRACT FROM AUTHOR] |
