This communication reports a dual regulation strategy, i.e., swelling and stiffness mismatch, for the shape morphing of calcium-alginate/polyacrylamide (PAAm) tough hydrogels enabled by site-specific patterning of ferric ions. Complex 3D or even 4D folding of tough hydrogels is achieved by sequentially applying the dual regulation.
本通讯报道了一种双重调控策略，即溶胀与刚度失配，用于通过铁离子的位点特异性图案化实现的海藻酸钙/聚丙烯酰胺（PAAm）坚韧水凝胶的形状变形。通过依次应用双重调控实现了坚韧水凝胶复杂的3D甚至4D折叠。
