Robust superhydrophobic TiO₂@fabrics for UV shielding, self-cleaning and oil–water separation

Abstract

Multifunctional robust TiO2@fabrics with special wettability demonstrated potential applications for excellent UV shielding, effective self-cleaning, efficient oil–water separation and microfluidic management.

Designing durable and flexible superhydrophobic coatings and its application in oil purification

“…Durable superhydrophobic coatings have been reported recently, 26 such as acrylic polyurethane based coating, 27 textured surface obtained by chemical etching, 28,29 surfaces template from innately microstructured hydrogel matrix, 30 block-copolymer-based thin-film patterning, 31 combination of rodlike palygorskite and organosilanes via spray-coating, 32 fluorine-free polysiloxane/multiwalled carbon nanotubes, 33 titanium dioxide materials with special wettability, 34 or various coatings fabricated on fabrics/sponges/cotton. [35][36][37][38][39][40] However, most of the reported surfaces are not durable enough, as they can only resist abrasion against wipes, 28 fine sandpaper (e.g., 800, 1000, 2000 grid), mild droplets/sand impinging, 30,31 or were easily disabled after a short distance (i.e., less than 5 m) of abrasion. 27,29,[41][42][43] Besides, the mechanical stability may be simply due to the fact that the coating thickness is too thick to be worn out completely to expose the substrate surface underneath the superhydrophobic coating.…”

Materials design towards sport textiles with low-friction and moisture-wicking dual functions

“…6 Ag NPs were also synthesized on fabric surface to achieve good color fastness, antimicrobial property and UV protection. 7 Yu et al found that multifunctional metal commingled yarns composed of antibacterial nylon/polyester/stainless steel wires could achieve good moisture wicking and antibacterial properties.…”

Preparation of Robust Superhydrophobic Halloysite Clay Nanotubes via Mussel-Inspired Surface Modification

“…However, the smooth PDA coatings obtained by typical method can hardly form primary obvious hierarchical structure, thus with the following secondary reaction, only hydrophobic surfaces would be achieved [35]. Various nanoparticles including noble metal (Ag) [36], metallic oxide (Fe 3 O 4 ) [37], and silicon oxide [38] were incorporated through the catechol coordinate bonds and hydrogen bonds to create primary hierarchical structures on HNTs surfaces, however, this most-used approach suffered from a lot of disadvantages, such as high cost, time-consuming, and poor stability. Therefore, a direct way to control the roughness of PDA coatings without incorporation of nanoparticles was urgently needed.…”
