Membrane separation processes are prevalent in industrial wastewater treatment because they are more effective than conventional methods at addressing global water issues. Consequently, the ideal membranes with high mechanical strength, thermal characteristics, flux, permeability, porosity, and solute removal capacity must be prepared to aid in the separation process for wastewater treatment. Rubber-based membranes have shown the potential for high mechanical properties in water separation processes to date. In addition, the excellent sustainable practice of natural fibers has attracted great attention from industrial players and researchers for the exploitation of polymer composite membranes to improve the balance between the environment and social and economic concerns. The incorporation of natural fiber in thermoplastic elastomer (TPE) as filler and pore former agent enhances the mechanical properties, and high separation efficiency characteristics of membrane composites are discussed. Furthermore, recent advancements in the fabrication technique of porous membranes affected the membrane’s structure, and the performance of wastewater treatment applications is reviewed.

Heat preservation, breathability, and unidirectional liquid penetration properties of wearable materials are vital for personal thermal management applications. Herein, flexible wearable Kevlar aerogel membranes with breathable and unidirectional liquid penetration properties were fabricated by underwater protection spraying of PDMS-trichlorotoluene onto one side of a Kevlar aerogel membrane and magnetron sputtering of Al nanoparticles on the other side of a Kevlar aerogel membrane PDMS (Al-KAM-PDMS). The results indicated that the PDMS side played an important role in improving the unidirectional liquid penetration property due to the asymmetric wettability property and an aerogel structure. To simulate unidirectional liquid penetration, simulated sweat can be penetrated from the PDMS side to the Al side of Al-KAM-PDMS within 14.4 s, implying excellent permeability. The Al side with high infrared reflectivity (72.77%) demonstrates that infrared radiation can be reflected back to the human body to achieve passive heating. An infrared image shows that Al-KAM-PDMS enables a simulated skin temperature decrease of 5 °C under a low temperature environment as compared to the Kevlar aerogel. The introduction of PDMS into Al-KAM-PDMS endows the membrane with high tensile stress of 5.60 MPa. In addition, Al-KAM-PDMS also possesses excellent breathability, showing its potential in wearable materials. Because of the exceptional unidirectional liquid penetration, breathability, and radiant heat insulation ability, Al-KAM-PDMS is a promising wearable material to help maintain a comfortable microclimate for individuals in outdoor environments.

“…The porous cellulose membranes were widely used in WIS to separate immiscible liquids owing to its good water‐wetting behavior and high drainage capability. [ 12 ] However, infused water mostly wicked into the porous body structure, depleting the water lubrication at the interface between the membrane and the target liquids (i.e., oil). The surface might result in oil fouling and lubricant loss.…”

Slippery, Water‐Infused Membrane with Grooved Nanotrichomes for Lubricating‐Induced Oil Repellency

et al. 2022

Water, abundant and ubiquitous in nature, is an easy yet powerful resource for the creatures to survive by putting together with their topologies interfacing their living environment. Here, a slippery, water-infusing surface (SWIS) that retains a thick and stable water layer on the membrane is presented, robustly maintaining the oil repellency against the pressure and friction of immiscible liquids. Inspired by the plant trichome structures and their function, grooved nanotrichome, formed on the fibrous membrane by the oxygen plasma etching, induces robust water lubrication on the SWIS. SWIS membrane repels and separates highly viscous and adhesive oils in air and underwater by preventing oils from adhering to the lubricating surface. Repeated tests both in air and underwater confirm the antiadhesion and self-cleaning properties of the SWIS. The SWIS oil scooper, fixed on a frame with a handle, successfully collects spilled oil on a pilot-scale oil spill site and a real ocean oil spill site by simply scooping and recovering the oil. In addition, SWIS membrane is expected to help protect environments with further applications such as oil-wastewater treatment and oil separation in food.
