“…The pollutants attached to the surface of the separation materials have been effectively degraded by visible light catalytic degradation of the composite materials prepared in this study, and the recycling of the materials has been realized. No obvious residues remained on the surfaces of the Ag-TiO 2 @PDMS coated cotton fabric, indicating that the Ag-TiO 2 @PDMS coated cotton fabric exhibited excellent anti-pollution properties (Cai et al 2020;Tang et al 2021).…”

Multifunctional materials for water purification have attracted great attention due to the increased water pollution problems. However, fabricating the low-cost and recyclable separation material is still a challenge. Herein, we developed an Ag/TiO2@PDMS coated cotton fabric with self-clean ability, high flux, superior visible-light photocatalysts ability, and recyclability via the “powder + glue” strategy. The composites exhibit superhydrophobic (water contact angle 157°), and high separation efficiency. The separation efficiency of 20 times of repeated use remains 16322 Lm−2h−1 and the degradation rate of methylene blue (MB) remains almost no change. The high oil purification, catalytic property, excellent stability in harsh condition and recyclability enables the material as a satisfactory candidate for water purification.

“…Superhydrophobic coatings with high contact angles (CA > 150°) and low-sliding angles (SA > 10°) of water have attracted much attention because of their many potential applications ( Nakajima et al, 1999 ), such as self-cleaning ( Guldin et al, 2013 ; Stieberova et al, 2017 ), oil/water separation ( Ye et al, 2017 ; Tang et al, 2021 ), anti-fogging ( Chevallier et al, 2011 ; Chang et al, 2012 ), anti-corrosion ( Liu et al, 2007 , 2010 ), anti-biofouling ( Lopez et al, 2016 ; Baidya et al, 2017 ), and anti-icing ( Emelyanenko et al, 2017 ; Wang et al, 2017 ). According to the Wenzel and Cassie–Baxter models, materials with micro- or nano-scale surface roughness and low-surface energies are both critical to the preparation of superhydrophobic surfaces ( Wenzel, 1936 ; Wang and Jiang, 2007 ).…”

The fabrication of an eco-friendly, multi-functional, and mechanically robust superhydrophobic coating using a simple method has many practical applications. Here, inspired by shell nacre, the micro- or nano-scale surface roughness that is necessary for superhydrophobic coatings was formed via Bacillus subtilis–induced mineralization. The biomineralized film coated with hexadecyltrimethoxysilane (HDTMS) exhibited superhydrophobicity with water contact angles of 156°. The biomimetic HDTMS/calcite-coating showed excellent self-cleaning, anti-icing, and anti-corrosion performances. Furthermore, mechanically robust superhydrophobicity could be realized by hierarchically structured biomineralized surfaces at two different length scales, with a nano-structure roughness to provide water repellency and a micro-structure roughness to provide durability. Our design strategy may guide the development of “green” superhydrophobic coatings that need to retain effective multi-functional abilities in harsh marine environments.

Oil-spill is one of the major global issues facing society in this century. The aim of this study was to develop a steel-based membrane for selective separation of oil from oil/water mixture. For this purpose, a single-step, rapid and environmentally friendly closed-batch initiated chemical vapor deposition (iCVD) method was employed to deposit hydrophobic thin film on a stainless-steel mesh. Perfluorodecyl acrylate (PFDA) and tert-butyl peroxide (TBPO) were used as monomer and initiator, respectively. Owing to the inherent vapor-based nature of iCVD method provided excellent conformal coverage on the mesh with high durability. iCVD coated mesh showed 96% oil/water separation efficiency. Highly reproducible results were obtained when the oil/water separation experiments were repeated.
