Intense investigations have been attracted to the development of materials which can recon-figure into 3D structures in response to external *** we report on the design and self-folding behaviors of hydrogels composed of poly(ethylene glycol)methyl ether methacry-late(OEGMA)and 2-(2-methoxyethoxy)ethyl methacrylate(MEO2MA).Upon immersion into a variety of solvents at room temperature,the resulting P(MEO2MA-co-OEGMA)hy-drogel sheets self-fold into 3D morphologies,and the observed transformation in shape is *** further show that composition of the gel,gaseous environment,and prepara-tion procedure play important roles in the self-folding behavior of the resulting *** work provides a facile approach for fabricating self-folding hydrogels.
