Self-healing of Poly(2-hydroxyethyl methacrylate) hydrogel through molecular diffusion

Synthetic materials that are capable of healing upon damage are being developed at a rapid pace because of their many potential applications. Here, new healing chemically cross-linked hydrogel of poly(2-hydroxyethyl methacrylate) (pHEMA) was prepared. The healing hydrogel was achieved by heating abo...
