Fluorine-Functionalized Covalent Organic Framework Superhydrophobic Modified Melamine Sponge for Efficient oil–water Separation

Abstract

Hydrophobic sponges have attracted significant interest in oil spills and water−oil separation as potential absorption materials due to their desirable absorptivity, selectivity, and elasticity. In this paper, a hydrophilic melamine sponge (MS) is transferred into a superhydrophobic sponge via polydimethylsiloxane (PDMS) modification followed by in situ growth of fluorine-functionalized covalent organic framework (denoted as TFA-COF) nanoparticles. Therefore,

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.…”
