Solvent Exchange Strengthening Interpenetrating Dual-Network Organohydrogels with Anti-icing Durability and Friction Resistance.

ABSTRACT: Developing mechanically robust hydrogels with low ice adhesion and anti-icing durability in low-temperature environments (≤ -20 °C) remains a persistent challenge. In this study, a dual-network organohydrogel (PAD) was synthesized through a facile one-pot copolymerization of acrylamide (AM), and [2-(Methacryloyloxy)-ethyl]-trimethylammonium chloride (DML) dissolved in poly-(vinyl alcohol) (PVA) aqueous solution, followed by solvent exchange in a mixed solvent of dl-1,2-Isopropylideneglycerol-(ACM) and water (H₂O). This unique solvent exchange enhances chain entanglement within the interpenetrating dual networks and establishes robust hydrogen bonding interactions. The optimized organohydrogel exhibits a mechanical strength of 0.8 MPa and an elongation at break of 450%, significa
