Surface engineering of a superamphiphilic, self-growing fibrous Janus membrane prepared from mycelium

Abstract

The increasing demand for effective oil–water separation materials has encouraged the exploration of sustainable and ecofriendly solutions. In this study, we investigate the surface engineering of a superamphiphilic, self-growing fibrous...

Superhydrophilic–superhydrophobic integrated system based on copper mesh for continuous and efficient oil–water separation

“…The achieved superhydrophobic/superoleophilic surfaces could enable efficient separation of oil–water mixtures. 17–21 In 2004, Jiang et al 22 first reported the use of superhydrophobic/superoleophilic porous stainless steel mesh membranes for oil–water separation. Moreover, separation membrane materials exhibiting superhydrophilic/underwater superoleophobic properties have been widely investigated for the treatment of oily wastewater.…”

Fast Sweat Wicking Enabled by Unidirectional Water Transport in Biodegradable Trilayered Porous Membranes Produced via Papermaking

“…36 Natural fibrous membranes and the exploitation of their hydrophilic or hydrophobic nature in various applications are rising. Cavalcante et al demonstrated a new application of membrane contactors for developing superamphiphilic mycelium materials; 37 Chen et al reconstructed eco-friendly disposable tableware based on bamboo fiber separation and its network structure; 38 and Oldal et al used green solvents to prepare inherently sustainable CA nanofibers. 39 Herein, we propose, for the first time, a simple strategy to develop a functional textile based on trilayered porous membranes with unidirectional water transport performance and complete degradation for continuous moisture wicking (Figure 1a).…”

Used Cooking Oil-Derived Fluorinated Porous Polysulfide Materials for Oil Spill Remediation: A Waste-to-Wealth by Sustainable Initiative

“…However, most of the high-performance sorbent materials are not cost-effective for large-scale production, and most of the commercially available sorbents are made from nonrenewable polyurethane foams or polypropylene fibers . Other suggested techniques such as nanofibrous gel composites, fluorinated graphene oxide, nonporous fluorinated polyimides, fluorine-functionalized covalent organic framework, MOF-based porous materials, , poly­( N -isopropylacrylamide) hydrogel, fabric materials, cellulose aerogel, composite membranes, and Janus membranes − are used for oil–water separation. Also, phase-selective oleogelators (PSOGs) , are not practically accessible since it is difficult to apply the gelator uniformly and remove the delicate gel-like mass of congealed oil from the surface of sea. − Therefore, the development of an efficient and feasible scalable technique to tackle oil spills is urgently needed.…”
