Pure Zwitterionic Hydrogel with Mechanical Robustness and Dynamic Tunability Enabled by Synergistic Non‐Covalent Interactions

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

Published: July 31, 2024

Abstract Zwitterionic hydrogels with exceptional antifouling properties and biocompatibility have gained widespread attention in biomedical applications. However, achieving robust mechanical performance while maintaining high water content within a single‐network zwitterionic hydrogel remains challenging. Traditional covalent crosslinking strategies often lead to brittleness irreversible damage. Herein, novel acylsemicarbazide‐containing carboxybetaine methacrylate (ACBMA) monomer is designed synthesized that enables the construction of pure poly(ACBMA) (pACBMA) without chemical crosslinkers. The pACBMA exhibits exceeding 95% superior properties, including compressive fracture stress 3.92 MPa, strain up 99% breaking, toughness 212 ± 2.4 kJ m − 3 , outperforming chemically crosslinked poly(carboxybetaine methacrylate) (pCBMA) hydrogel. Additionally, excellent injectability, moldability, even recyclability through preparation microgels. Through unique molecular design, integrates multiple non‐covalent interactions, hydrogen bonding, electrostatic polymer chain entanglement, steric hindrance α ‐methyl group. These interactions synergistically contribute combination hydration, robustness, dynamic tunability. results provide new design strategy for constructing high‐performance promising potential diverse

Endocytosis‐Inspired Zwitterionic Gel Tape for High‐Efficient and Sustainable Underoil Adhesion

Advanced Science, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 9, 2024

Abstract Marine oil exploration is important yet greatly increases the risk of leakage, which will result in severe environment pollution and economic losses. It an urgent need to develop effective underoil adhesives. However, realizing adhesion even harder than those underwater, due stubborn attachment a highly viscous layer on target surface. Here, inspired by endocytosis, tough gel tape composed zwitterionic polymer network surfactants developed. The amphiphilic can form micelle capture droplets transport them from interface via electrostatic attraction backbone, mimicking endocytosis achieving robust adhesion. Benefiting oil‐resistance further realizes combination i) long‐term with high durability, ii) repeated oil, iii) renewable efficiency after exhausted use. exhibits ultra‐high adhesive toughness 2446.86 J m −2 stainless steel silicone 30 days' oil‐exposure; such value surpasses many achieved underwater greater performance commercial tape. strategy illustrated here motivate design sustainable efficient adhesives for wet environments.

High Strength, Swelling Resistance, Antimicrobial and Conductive Zwitterionic Hydrogel Based on Cellulose Frame

ACS Applied Polymer Materials, Journal Year: 2024, Volume and Issue: 6(11), P. 6603 - 6613

Published: June 5, 2024

A high strength, swelling resistance, and conductive hydrogel with excellent photothermal effect antimicrobial property is prepared based on a cellulose frame. First, dissolved in NaOH/urea aqueous solution. The solution self-assembled an ethanol environment to form frame then immersed the acrylamide (AM) 2-methylacryloxyethyl phosphocholine (MPC) Cel-PAxMy by situ copolymerization of AM MPC. Lastly, soaked tannic acid/ferric chloride (TA@Fe3+) prepare TA@Fe3+-Cel-PAxMy hydrogel. obtained shows mechanical strength (toughness 600 KJ/m3, Young's modulus 225 KJ/m3) due presence rigid introduction TA@Fe3+ not only increases cross-linking density hydrogels, making hydrogels have extraordinary resistance (swelling ratio 50 ± 20%), but also endows electrical conductivity (conductivity 1.0 S/m, GF 0.75, response time 572.27 ms), good near-infrared effect, outstanding property. This work proposes effective strategy for development zwitterionic hydrogel, which exhibits significant promise wearable sensors electronic devices.
