Wood is still a widely used raw material in many fields and is surface-modified for diverse applications. Though a few studies reported the anti-fungal effect derived from enhanced hydrophobicity of wood surface, no report about the influence of superhydrophobic surface upon fungi is known and the comparison of anti-fungal effects between hydrophobicity and superhydrophobicity on wood surface has...
Superhydrophobic cotton fabrics consisting of tea polyphenol/Fe hybrid coatings on cotton fabrics (TP/Fe@cotton fabrics) were fabricated via a facile, highly efficient, and environmentally friendly method. No fluorinated substances or organic solvents were used in the preparation process that involved only Fe2+, natural substances, and water. The original and modified cotton fabrics were characterized...
With the massive discharge of industrial oily wastewater and the frequent occurrence of oil spills at sea in recent years, the fabrication of superhydrophobic and durable oil-absorbing materials is urgently required for oil recovery and disposal of oily water in practical applications. In this paper, ultralight, elastic, superhydrophobic and durable carbon fiber aerogels (CFAs) derived from sisal...
A modified cotton fabric with both flame-retardant and superhydrophobic properties was prepared using copper, 2,5-dimercapto-1,3,4-thiadiazole, silver and octatriethoxysilane via trilayer coatings over the cotton fabric. The surface morphology of the cotton fabric before and after coatings was investigated by scanning electron microscopy. The wetting behaviour of the as-modified cotton fabrics was...
A multi-functional cotton fabric with UV resistance, antibacterial and superhydrophobic properties was achieved by immobilizing metal–organic framework ZnBDC on the fabric surface using zinc(II) acetate and 1,4-benzenedicarboxylic acid as raw materials. The immobilization of ZnBDC was performed via water-based layer-by-layer (LbL) deposition based on the concept of self-assemble. The ZnBDC on cotton...
In this research, a one-step method for the preparation of superhydrophobic and antibacterial cotton fabric is presented, which has been modified by zinc oxide (ZnO) nanoparticles and octadecanethiol (ODT). The individual use of ZnO and ODT resulted in superhydrophilic fabrics whereas their combined use caused a transformation to the superhydrophobic behavior. Based on the morphological analysis,...
This article reports robust technology for converting tissue paper (TP) into an efficient separation membrane by coating with a novel superhydrophobic material that was synthesized by a rapid, one step approach without using any hazardous chemicals viz fluorinated materials or organic/inorganic nanoparticles. The coating was prepared using modified cellulose nanofibers which can readily transform...
Biomass-derived carbon aerogels with 3D network porous structure show excellent physical properties and exhibit superior application potential. Here, we prepare multifunctional carbon aerogels (MCAs) by carbonization of aerogels composed of typha orientalis fibers. The MCAs feature light mass (5.0 mg cm−3), excellent compressibility (80%), good electrical conductivity (0.18 S cm−1), and very high...
Superhydrophobic material involves the fabrication of appropriate roughness and low surface energy. Studies concerning enhancing the attachment between substrates and low surface energy material have been reported. Hence, it might also be feasible to make low surface energy material as an interface binder to enhance the attachment. In our work, the simple dip-coating method was used to fabricate polybenzoxazine...
