Shape-memory properties of hydrogels having a poly(ε-caprolactone) crosslinker and switching segment in an aqueous environment

► Shape-memory hydrogels with crystallizable poly(ε-caprolactone) switching domains. ► The shape-memory effect was explored in an aqueous environment. ► The crystallization was studied by in situ X-ray scattering experiments. ► The orientation of the crystalline domains controlled the shape-memory effect.
