“…The CA of treated cotton fabric could reach 150° showed excellent water repellency, and water drop could be maintained on cotton fabric sample for tens of seconds without wetting. The silica skeleton played a certain role in protective layer formed, and there were many Si‐CH 3 in PNCTSi, which can reduce the surface energy of cotton fabric …”

A novel cyclic‐shaped multifunctional copolymer named poly[tetra(tetramethylcyclosiloxyl‐piperazin)‐phosphinic acid methyl ether] (PNCTSi) was successfully synthesized. Its flame‐retardant and hydrophobicity properties on cotton fabrics were investigated. The limited oxygen index (LOI) value of treated cotton fabrics with PNCTSi was up to 29.8%. By vertical burning test, it was found that the treated cotton fabrics have no after‐flame and no after‐glow. Apparently, more amounts of char were generated and hazardous volatiles distinctly reduce after combustion by thermogravimetric analysis. Besides, Treated cotton fabrics with PNCTSi can give a hydrophobic property, which reach a contact angle of 150°. The surface morphology of treated cotton fabric before and after combustion was analyzed by scanning electron microscopy, after burned, the surface morphology of cotton fiber exhibited more smooth and expanded feature. After washing the cotton fabric for 20 times, the LOI remains at above of 26.0%. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47280.

“…Very recently Xu et al fabricated superhydrophobic fabric via the polymerization of dopamine in alkaline solution with Ag deposition and subsequent modification with 1H,1H,2H,2H-Perfluorodecanethiol [16]. The resulting coated fabric efficiently separated oil from oil-water mixture owing to its superhydrophobicity and superoleophilicity.…”

“…The similar approach has been reported for reducing Ag ion to Ag nanoparticles on PDA-coated surfaces, which demonstrated the excellent adhesion and stability. 19 The PDA assemblies and Ag nanoparticles and clusters served as building blocks of the micro/nano multiscale hierarchical structure and accordingly generated high surface roughness on wood substrates (Fig. 1c).…”

A facile and versatile mussel-inspired surface modification approach was used to modify porous materials (wood, sponge and stainless steel mesh) to fabricate a superhydrophobic surface. The as-formed polydopamine (PDA) coating can tightly adhere on the porous structure surface, which also provides a versatile platform for secondary reactions to anchor hydrophobic long-chain groups for hierarchical superhydrophobic surfaces preparation. The as-prepared surfaces showed excellent superhydrophobicity with a water contact angle (CA) of about 153 , even after being subjected to harsh conditions, including strong acid-base and organic solvent immersion, high-temperature boiling, ultrasonic washing, and ultraviolet aging. The produced superhydrophobic sponge exhibited an oil absorption capacity of 73-156 times its own weight for a series of oils and organic solvents and showed good recyclability. The obtained stainless steel mesh also presented good oil-water separation ability. Importantly, this modification method provides an efficient, versatile, easy, and mild route to prepare superhydrophobic surfaces for various porous substrates, resulting in a wide range of potential applications.
