Abstract

A fully physically linked poly(acrylic acid) (PAA) hydrogel with temperature sensitivity was fabricated. The temperature-sensitive point of the hydrogel was near 25 °C when introducing the copolymer of N-isopropylacrylamide (NIPAAM) and dopamine methacrylamide (DMA). More importantly, the hydrogels exhibited excellent self-healing properties, mechanical properties and tunable adhesive strength and could be used as epidermal sensors.
