Development of an Easy-To-Synthesize Self-Healing Gel Composed of Entangled Ultrahigh Molecular Weight Polymers
—Circular-Economy-Friendly Gel May Be Used in Durable Flexible Devices—

A research team consisting of NIMS, Hokkaido University and Yamaguchi University has developed a method for easily synthesizing a self-healing polymer gel made of ultrahigh molecular weight (UHMW) polymers (polymers with a molecular weight greater than 106 g/mol) and non-volatile ionic liquids.
