“…Ahmad et al prepared a superhydrophobic cotton fabric by immobilizing nanoparticles with a silane (APTES) coupling agent to provide proper roughness and introducing myristic acid, a low surface energy substance. Zhu et al developed a superhydrophobic cotton fabric composed of phytic acid/3-aminopropyltriethoxysilane (PA/APTES), carbon nanotubes (CNT), and polydimethylsiloxane (PDMS). However, most superhydrophobic cotton fabrics are prepared using environmentally harmful fluoride or silane compounds and are monofunctional. − This no longer meets the green sustainability needs of today’s world.…”

Superhydrophobic cotton fabrics have a lot of potential for use in practical settings. The majority of superhydrophobic cotton fabrics, however, only serve one purpose and are made from fluoride or silane chemicals. Therefore, it remains a challenge to develop multifunctional superhydrophobic cotton fabrics using environmentally friendly raw materials. In this study, chitosan (CS), amino carbon nanotubes (ACNTs), and octadecylamine (ODA) were used as raw materials to create CS-ACNTs-ODA photothermal superhydrophobic cotton fabrics. The cotton fabric that was created showed a remarkable superhydrophobic property with a water contact angle of 160.3°. The surface temperature of CS-ACNTs-ODA cotton fabric can rise by up to 70 °C when exposed to simulated sunlight, demonstrating the fabric’s remarkable photothermal capabilities. Additionally, the coated cotton fabric is capable of quick deicing. Ice particles (10 μL) melted and began to roll down in 180 s under the light of “1 sun”. The cotton fabric exhibits good durability and adaptability in terms of mechanical qualities and washing tests. Moreover, the CS-ACNTs-ODA cotton fabric displays a separation efficacy of more than 91% when used to treat various oil and water mixtures. We also impregnate the coating on polyurethane sponges, which can quickly absorb and separate oil and water mixtures.

“…To solve this problem, two main strategies have been proposed. Some researchers attempted to reduce the viscosity of the surrounding crude oil with an external heating source, e.g., joule-heating [13][14][15] , photothermal conversion 14,[16][17][18] , electromagnetic induction 19,20 . The other strategy was the fabrication of superhydrophilic/ underwater superoleophobic membranes which have been deserved more attention 21 .…”

Complex pollutants are discharging and accumulating in rivers and oceans, requiring a coupled strategy to resolve pollutants efficiently. A novel method is proposed to treat multiple pollutants with C,N co-doped TiO2 hollow nanofibers coated stainless steel meshes which can realize efficient oil/water separation and visible light-drove dyes photodegradation. The poly(divinylbenzene-co-vinylbenzene chloride), P(DVB-co-VBC), nanofibers are generated by precipitate cationic polymerization on the mesh framework, following with quaternization by triethylamine for N doping. Then, TiO2 is coated on the polymeric nanofibers via in-situ sol–gel process of tetrabutyl titanate. The functional mesh coated with C,N co-doped TiO2 hollow nanofibers is obtained after calcination under nitrogen atmosphere. The resultant mesh demonstrates superhydrophilic/underwater superoleophobic property which is promising in oil/water separation. More importantly, the C,N co-doped TiO2 hollow nanofibers endow the mesh with high photodegradation ability to dyes under visible light. This work draws an affordable but high-performance multifunctional mesh for potential applications in wastewater treatment.

In this study, a carbon nanotube:multilayer graphene (CNT:G) hybrid nanofiller was constructed and recycled poly(ethylene terephthalate) (rPET) based composite nanofibers containing CNT, or CNT:G were electrospun and characterized in order to fabricate thermally conductive polymer nanomats. Particular attention was directed toward investigating the effects of CNT and CNT:G in enhancing thermal stability, thermal conductivity coefficient, and heat dissipation efficiency of the composite nanofibers. The thermal conductivity coefficient of neat rPET nanofibers was found as 12.753 W/mK while it increased to 34.437, 38.713, and 96.957 W/mK with 0.25%, 1%, and 5% of CNT incorporation, respectively. When hybrid nanofillers were used at a loading of 1%, the thermal conductivity coefficients for rPET/CNT:G nanofibers with CNT:G ratios of 1:1 and 1:3 respectively increased to 62.229, and 47.62 W/mK. The heat dissipation efficiency of the rPET nanofibers was also enhanced upon nanofiller incorporation which was illustrated with infrared thermography data. The results suggest the use of both CNT‐ and CNT:G‐loaded rPET composite nanofibers as promising textile materials for passive cooling applications.Highlights Hybrid CNT:G nanofillers are synthesized with weight ratios of 1:1 and 1:3. rPET/CNT and rPET/CNT:G composite nanofibers are electrospun. The thermal conductivity coefficients of the composite nanofibers are improved. The composite nanofibers are also mechanically enhanced. Value‐added rPET products as thermal management materials are proposed.
