a Optical images of the peeling process; the scale bar is 0.5 cm. b Curves of the peeling force per width versus displacement for the various types of hydrogel-plastic hybrids. c Measured interfacial toughness values of the hybrids. d Digital picture of the tensioning process; the scale bar is 0.5 cm. The inset shows its original state. e Tensile stress of the hybrids based on ABS, PVC and PP. f Statistical tensile stress of the hybrids.
