“…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.

“…Fabricating a superhydrophobic surface on cotton fabrics has been extensively studied, which has been demonstrated as an effective method in the functionalization of cotton fabrics for self-cleaning [4,5] and oil/water separation [6][7][8][9][10]. The superhydrophobic surface on cotton fabrics could be realized by various techniques, including the CVD (chemical vapor deposition) method [11][12][13], sol-gel process [3,14,15], solution immersion [16,17], spray deposition [18][19][20], and graft polymerization [1,12,[21][22][23][24][25]. Two essential factors for the fabrication of a superhydrophobic surface on cotton fabrics are (i) rough surface and (ii) low surface energy.…”

“…Two essential factors for the fabrication of a superhydrophobic surface on cotton fabrics are (i) rough surface and (ii) low surface energy. To build a rough surface on cotton fabrics, inorganic nanoparticles such as ZnO [26], TiO 2 [6,7,15,27], and SiO 2 [2,14,28] were employed. Since the inorganic nanoparticles were generally very hydrophilic, a further hydrophobic modification process should be carried out to lower the surface energy of the resultant rough surface.…”

Highly hydrophobic cotton fabrics were obtained with poly(methylhydrogen)siloxane (PMHS) and a further fluorinated olefin modification. The chemical structures and microstructures of PMHS-modified cotton fabrics were characterized, and application of the resultant cotton fabrics in stain resistance and oil–water separation was demonstrated. PMHS chains with very low surface energy were grafted onto cotton fabric by the dehydrogenation reaction between –Si–H of PMHS and –OH groups of cotton fabric at room temperature. The water contact angle of PMHS-modified cotton fabric was 141.7°, which provided the modified cotton fabric with good stain resistance to waterborne pollutants. The separation efficiency of diesel from water was higher than 92% for 20 repeatable separation cycles. A further improvement in stain resistance to oil was also demonstrated by a further addition reaction of 1H,1H,2H-perfluoro-1-decene with PMHS-modified cotton fabric.

“…To our knowledge, the superhydrophobic surface can be achieved by the following two approaches: (1) the creation of a suitable hierarchical roughness, and (2) the chemical modification of rough surfaces with low surface energy materials [6][7][8]. In order to create the suitable hierarchical roughness, methods such as sol-gel [9], layer-by-layer assembly [10,11], chemical vapor deposition [12], and electrochemical processes [13] have been reported. Low surface energy materials such as fluorosilane [14], plasma and organosilanes [15], and perfluorinated compounds [16] have been used to perform chemical modification.…”

The poor durability and complex production process are two tough challenges for the practical application of superhydrophobic wood. In this work, high-mechanical-resistance superhydrophobic wood was fabricated by a one-step hydrothermal vacuum dipping method using SiO 2 nanoparticles (SiO 2 NPs) in combination with vinyltriethoxysilane (VTES). The as-prepared superhydrophobic surfaces exhibited water contact angles (CAs) greater than 152 • and water sliding angles (SAs) less than 3 • . It also exhibited robust stability and durability in harsh conditions, including finger wiping, water brushing, intense sandpaper abrasion, and severe ultrasonic cleaning. The superhydrophobic surface was created by the random distribution of oligomer-wrapped SiO 2 NP spheres having different sizes. Further testing showed that the SiO 2 NPs were firmly fixed on the wood substrate via chemical bonding, which contributed to the high wear resistance. The modification method developed in this work provides a simple and efficient route to fabricate large-scale, mechanically stable, and durable superhydrophobic surfaces for advanced engineering materials.
