A superhydrophobic fabric coating with hierarchical structure was fabricated by a dip coating, in which dodecyltrimethoxysilane (DTMS)‐modified alumina (Al2O3) was used as modifier and polydimethylsiloxane (PDMS) as additive. The effects of the amounts of Al2O3 nano‐sized particles and PDMS on the water contact angle (WCA) and the sliding angle (SA) of the as‐prepared fabrics coating samples were studied. The surface morphology of the as‐prepared samples was characterized by SEM, and the abrasion resistance and chemical resistance experiments were performed by abrasion resistance test, tape tear test, and chemical soaking test. The results show that WCA and SA of the superhydrophobic fabrics coating are 158° and 6°, respectively. With the increasing addition of PDMS, the abrasion resistance of hydrophobic fabrics coating is improved. The WCA value of the as‐prepared fabrics coating is still >150° after five abrasion cycles. The obtained fabrics exhibit excellent superhydrophobicity and oleophilicity due to the hydrophobic modification of DTMS for Al2O3 nano‐sized particles. And the separation efficiency of the as‐prepared superhydrophobic fabrics coating for n‐dodecane and water system can reach 99.98%. POLYM. COMPOS., 2018. © 2018 Society of Plastics Engineers

“…Desirable properties in waterborne coatings include flexibility [ 29 , 88 , 117 ], adhesion [ 81 , 118 , 119 ], wear resistance [ 92 , 102 , 120 , 121 , 122 ], and durability [ 120 ]. Among the possibilities for added coating functionality are, for example, flame retardancy [ 119 ], solvent and chemical resistance [ 123 , 124 ], stain resistance [ 102 , 124 ], anti-cavitation [ 81 ], extreme robustness (for space-based applications) [ 125 ], antimicrobial activity [ 126 , 127 , 128 , 129 , 130 , 131 ], superhydrophobicity [ 84 , 95 , 124 , 132 , 133 , 134 , 135 , 136 , 137 , 138 ], or photoactive fluorescent coatings [ 29 ] presented in Table 3 .…”

“…This is an extremely interesting property, with application in self-cleaning, anticorrosion, antipollution, self-healing, and ice repellent surfaces [ 142 ]. Coatings with contact angles above 150° have been prepared using nanoparticles modified with different hydrophobic groups (e.g., fluorinated) [ 124 , 133 , 134 , 135 , 136 , 138 ] and modulating the roughness of the surface (e.g., using raspberry-like structures) [ 95 , 115 , 132 ]. Nahum et al prepared nanocomposite coatings based on urethane acrylate and epoxy, containing SNPs functionalized with photoreactive benzophenone groups and a fluorinated silane [ 134 ].…”

“…These coatings are UV-cured to yield high contact angles and a good bonding between the SNPs and polymeric matrix. Water-repellent fluorine-free coatings were also reported, based on nanostructured roughness provided by the incorporation of SNP in polyester [ 124 ]. After treatment with poly(isobutylmethacrylate-co-3-methacryloxypropyltri-methoxysilane) (PIT), hydrophobic polyester fabrics with good water repellence were obtained ( Figure 9 ).…”

Combining organic and inorganic components at a nanoscale is an effective way to obtain high performance coating materials with excellent chemical and physical properties. This review focuses on recent approaches to prepare hybrid nanostructured waterborne coating materials combining the mechanical properties and versatility of silica as the inorganic filler, with the flexural properties and ease of processing of the polymer matrix. We cover silica-polymer coupling agents used to link the organic and inorganic components, the formation of hybrid films from these silica-polymer nanostructures, and their different applications. These hybrid nanostructures can be used to prepare high performance functional coatings with different properties from optical transparency, to resistance to temperature, hydrophobicity, anti-corrosion, resistance to scratch, and antimicrobial activity.

“…Some types of sol-gel systems also have bacteriostatic or antibacterial effects [16][17][18][19][20][21][22]. These systems are anatase-modified photoactive TiO2 coatings and sol-gel coatings with colloidal metals or metal compounds embedded in them, such as silver, silver salt, copper compound, zinc or quaternary ammonium salt [18], so sol-gel technology can be applied to textiles to develop various functional finishes with antibacterial [23][24][25][26][27][28][29][30][31][32], water repellent [33][34][35][36][37][38], superhydrophobic [39][40][41][42][43][44], oil/water separations [45][46][47][48][49][50][51][52][53], flame-retardant [54][55][56][57][58][59][60][61]…”

The commercial availability of inorganic/organic precursors for sol-gel formulations is very high and increases day by day. In textile applications, the precursor-synthesized sol-gels along with functional chemicals can be deposited onto textile fabrics in one step by rolling, padding, dip-coating, spraying or spin coating. By using this technology, it is possible to provide fabrics with functional/multi-functional characteristics including flame retardant, anti-mosquito, water- repellent, oil-repellent, anti-bacterial, anti-wrinkle, ultraviolet (UV) protection and self-cleaning properties. These surface properties are discussed, describing the history, basic chemistry, factors affecting the sol-gel synthesis, progress in sol-gel technology along with various parameters controlling sol-gel technology. Additionally, this review deals with the recent progress of sol-gel technology in textiles in addressing fabric finishing, water repellent textiles, oil/water separation, flame retardant, UV protection and self-cleaning, self-sterilizing, wrinkle resistance, heat storage, photochromic and thermochromic color changes and the improvement of the durability and wear resistance properties.
