Fish Scale-Inspired β-Cyclodextrin Cross-Linked Polyacrylamide Hydrogels for Oil–Water Separation

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: 17(11), P. 17389 - 17397

Published: March 5, 2025

Cyclodextrins (CDs), a low-polysaccharide class, possess hydrophilic outer surface due to their hydroxyl groups, which can be functionalized for various applications. In this study, the groups on β-cyclodextrin were with acrylates (CD-A) and subsequently used as cross-linker in copolymerization acrylamide form polyacrylamide-cyclodextrin hydrogel (PAC). Compared polyacrylamide (PAM), PAC exhibited enhanced water absorption abilities mechanical strength. Inspired by fish scales' structural properties, microporous stainless steel meshes coated PAC, we could demonstrate an excellent oil-water separation superhydrophilicity underwater superoleophobicity. The mesh effectively separated mixtures using gravity filtration, achieving efficiencies of over 99%. Repeated use different oil types confirmed durability effectiveness hydrogel-coated practical applications separation.

High‐Strength and High‐Stretchability All‐Solid‐State Double‐Network Ion‐conductive Elastomers Based on Supramolecular Deep Eutectic Polymer

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 9, 2025

Abstract The double‐network (DN) structure has been proven to be an effective approach enhancing the strength and stretchability of stretchable ionic conductors. However, conventional strategy using a rigid first network encapsulate loose second often suffers from insufficient poor stability in practical applications due presence solvents system or significant compatibility differences between two networks. Therefore, developing ion‐conductive elastomers with minimal strong environmental is critical addressing these challenges flexible electronics. This study leverages highly customizable all‐solid‐state supramolecular deep eutectic polymers design Poly ( N ‐(2‐Hydroxyethyl) acrylamide‐Choline chloride) (HEAA‐ChCl) as Poly(Acrylic acid‐Choline (AA‐ChCl) network, both exhibiting similar compatibility. ensures uniform embedding networks, enabling efficient energy dissipation under external forces. resulting elastomer achieves 13.8 MPa, tensile strain 2780%, toughness high 161 MJ m − 3 . Such strategy, its exceptional mechanical properties, provides robust support for advancing high‐strength intelligent manufacturing.
