Rational Designed Polymeric Rigid Cages for Trapping Bulky Vegetable Oils toward Versatile Bio‐Based Adhesives

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

Published: Oct. 18, 2024

Abstract Polymer gels stand out as emerging and promising materials in adhesives. However, flexible network network–solvent mismatch affect their strengths stabilities. Regulating the architectures of polymer via molecular design is a strategy to overcome these drawbacks. Herein, novel polymeric rigid cage (PRC) structure proposed for capturing bulky vegetable oils mechanically interlocking supramolecular interactions or steric hindrance effect fabricate universal gels‐based By rationally designing refining architectures, prepared by 4,4′‐diphenylmethane diisocyanate (MDI) N , ″, ″‐tetra(2‐hydroxypropyl) ethylenediamine (EDTP) possesses optimal encapsulation epoxidized linseed oil (ELO). The resulting RCE‐50 gel exhibited robust mechanical properties (≈65 MPa) excellent stability (high temperatures, high pressures, solvents immersion). Owing strength polyurethane network, adhesion high‐density amino ester groups, well hydrophobic toughening effects ELO, can be used versatile adhesive with under different conditions. This study proposes new approach innovating gels, provides idea porous materials, offers fresh insights developing bio‐based

Lanthanide‐Coordinated Multifunctional Hydrogel for Detecting Human Motion and Encrypting Information

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

Published: Jan. 2, 2025

Abstract Smart hydrogels with multi‐fluorescent properties hold great promise for information encryption. However, conventional fluorescent often lack adequate mechanical and multiple responsiveness, limiting their range of applications. In this study, a multifunctional hydrogel featuring an interpenetrating polymer network (IPN) composed poly(vinyl alcohol) (PVA) poly(acrylic amide‐co‐2‐acrylamido‐2‐methylpropane sulfonic acid) P(AM/AMPS) chemical cross‐linking networks is designed. Through the coordination lanthanide ions (Eu 3+ , Tb ) glycine, achieves exceptional stretchability (over 900%) adjustable photoluminescence properties. Due to acid groups on 2‐acrylamide‐2‐methylpropanesulfonic (AMPS), which support various noncovalent interactions, PVA‐P(AM/AMPS)‐Gly‐Ln displays strong reversible adhesive diverse substrates. Ultimately, assembled into multifunctional, flexible sensor, boasting satisfactory sensitivity (GF = 5.3), rapid response rate (100 ms), outstanding characteristics, highlighting its potential applications in human motion detection
