摘要

目前的共凝胶还存在机械强度和韧性较弱的缺点。在这里，利用深共晶溶剂（DES）和聚合物链之间丰富的非共价交联，制备了一类新的共凝胶。当液体质量大于60 wt%时，共凝胶表现出巨大的杨氏模量（655 MPa）、断裂强度（16 MPa）和韧性（46 MJ/m3）。

Ultra-stiff and tough glassy eutectogel

Current eutectogels still exhibit shortcomings in weak mechanical strength and toughness. Here, a new class of eutectogels facilely prepared by leveraging abundant noncovalent crosslinks between deep eutectic solvents (DES) and polymer chains. The eutectogels with more than 60 wt% liquid exhibit enormous Young’s modulus (655 MPa), fracture strength (16 MPa) and toughness (46 MJ/m3).
