The mechanical properties of the substrate elastomers are often poor due to the inherent performance of the materials. Researchers in China prepared a poly(vinyl alcohol) (PVA)-based self-healing material with high strength and good thermal stability by side-linked grafting modification of PVA with a one-step esterification reaction. Benefiting from the hydrogen bonds and ion coordination between iron ions and carboxyl groups, the synthesized elastomer exhibited excellent mechanical properties and good self-healing performance. The high sensitivity and self-healing performance of a silver nanowire-coated elastomer strain sensor demonstrated the wide potential applicability of the prepared PVA-based elastomers in health care, electrocardiography, and safety monitoring… read more.
