Elastic ionogel fibers have scored tremendous achievements with the rapid development of artificial intelligence and electronic techniques. However, conventional elastic materials usually suffer from poor mechanical strength, high cost, toxicity, pollution, which severely restrict their practical applications. To meet this challenge, we design a biobased fiber by using eco-friendly polymerizable deep eutectic solvents (PDESs) as substrate all-natural milk reinforcement. This milk-based PDES exhibits remarkable properties (7.52 MPa tensile stress) due to intrinsic hydrogen bonding interactions between molecular network protein, is three times much that pure fiber. Meanwhile, also shows extreme-environment resistance, can maintain most flexibility after being treated at −60 60 °C. More importantly, possesses self-healing property under humidity strain-sensing behavior, be utilized monitor human motion signals. work not only developed high-performance through low-cost green manner but promoted fundamental research industrialization flexible wearable materials.

We reveal that systematic variations chemical composition binary and ternary DESs dictate stabilization wide range conformations, is, compact globular folds, intermediate folding states, or unfolded chains, well controlling collective behavior. Besides, different visited by simply adjusting DESs, allowing for refolding vice versa. Notably, show these intermediates trigger formation supramolecular gels, also known eutectogels, where mechanical correlate state protein.
