Antifouling Polyvinylidene Fluoride Membrane through Dopamine Self‐Polymerization Enhanced Surface Segregation toward Oil‐In‐Water Emulsions Separation

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: June 6, 2024

Abstract Surface segregation method, as an in situ method for simultaneous modification of membrane external surfaces and inner pore surfaces, has been more commonly employed to fabricate antifouling membranes. In this study, dopamine (DA) with self‐polymerization bio‐adhesion ability is chosen a surface agent polyvinylidene fluoride (PVDF) oil‐in‐water emulsions separation through synergistically regulating phase inversion, DA, poly‐dopamine (PDA). During the inversion process, DA contacts alkaline coagulation bath trigger then PDA proceeds spontaneously. The addition can regulate process acquire membranes high porosity, result, water permeance increased from 134 538 L m −2 h −1 bar oil rejection higher than 99.8%. Because hydrophilic layer on leads robust hydration layer, exhibits super‐oleophobicity underwater excellent properties recovery ratio 99.4%. This study may open new route preparing by using small molecules agents.

Solvent-regulable interfacial groups enable on-demand superhydrophobic/superhydrophilic silica aerogels

Nature Communications, Journal Year: 2025, Volume and Issue: 16(1)

Published: March 5, 2025

Silica aerogel, as the earliest synthetic and commercially available one among all known aerogels, holds significant value in fields including thermal acoustic insulation, optics, catalysis, sorption, etc. However, throughout its nearly century-long history, influence of solvent used during synthesis on properties silica aerogels has been neglected, resulting inaccurate ambiguous performance evaluation. Herein, we have uncovered systematically investigated solvent-regulable interfacial groups that enable on-demand superhydrophobicity/superhydrophilicity aerogels. During either sol-gel transition or exchange process both required for aerogel synthesis, alteration from water to ethanol vice versa leads switch superhydrophilic Si-OH superhydrophobic Si-OEt reversely due reversible esterification, thus enabling superhydrophobic/superhydrophilic It is worth noting solvent-regulated hydrophilicity/hydrophobicity true regardless precursors (the mixture trimethoxymethylsilane (MTMS)/tetramethoxysilane (TMOS), MTMS/tetraethyl orthosilicate (TEOS), sodium methicosilicate (SMS)/TMOS), thereby indicating universality, which wakes up considerable attention producers involved Additionally, discovery also provides a green, economical, efficient way achieve with hydrophilic/hydrophobic specific
