Using a fluorine-free copper mesh with dynamically tunable wetting properties for high-flux separation of oil-water mixtures

Multifunctional Piezoelectric Yarns and Meshes for Efficient Fog Water Collection, Energy Harvesting, and Sensing

“…One method involves changing the wettability of the fibers on a fog collector to take advantage of both the hydrophobic and hydrophilic properties. [25] Wettability alteration on smart surfaces occurs in nature and has also been successfully implemented in various applications, such as droplet manipulation, [26] switchable surfaces, [27] oil-water separation, [28] liquid transport, [29] and thermal management. [30] Thakur et al [31] showed that switchable DOI: 10.1002/smsc.202400021 Given global water scarcity and the quest for sustainable energy, there's a pressing need for integrated approaches addressing water-energy interdependence worldwide.…”

Photoresponsive Electrospun Fiber Meshes with Switchable Wettability for Effective Fog Water Harvesting in Variable Humidity Conditions

“…Recently, innovative techniques have been utilized to create smart wettable materials that can reversibly switch wetting behavior . Switchable wettability has emerged as an interesting research direction because of its significance in applications such as self-cleaning, microfluidic devices, water collection, and oil–water separation. − Choi et al fabricated a dual-wettability surface using 3D assisted printing. They concluded that hierarchically structured surfaces balanced the main performance combination to optimize the laplace pressure, surface area, and drainage efficiency.…”

Multifunctional applications of amino functionalized Ti3C2Tx: high flux oil/water separation and dye removal

“…7,8 One category is superhydrophobic-superoleophilic materials, which can allow oil to easily penetrate into the material and block moisture, 9,10 and another category is superhydrophilic-underwater superoleophobic materials, which can permit water to penetrate through the material and block oil. [11][12][13] For the past few years, other materials for the separation of immiscible oil/water mixtures have been prepared using MXene, graphene oxide (GO), TiO 2 , chitosan, and MnCo 2 O 4 . [14][15][16][17] Simultaneously, oily wastewater is mainly composed of oil/water mixtures and soluble dyes in complex mixtures, requiring more innovative material development to achieve the purification of complex oily wastewater.…”
