Polypseudorotaxane-based 3D-printing hydrogels consisting of dimethacrylamide-poly(ethylene-glycol) and α-CD have been developed. After post-printing crosslinking, the 3D-printed polyrotaxane monolith exhibits rapid and reversible shape morphing upon pH variation. Copolymerization of the polypseudorotaxane with acrylates affords hybrid 4D printing materials that are responsive to pH and ionic strength.

通过pH控制的纳米环运动放大3D打印的聚轮烷整体结构的快速宏观形状形变†

已经开发了由伪甲基紫杉烷为基础的3D打印水凝胶，该凝胶由二甲基丙烯酰胺-聚（乙二醇）和α-CD组成。印刷后交联后，3D打印的聚轮烷整体料在pH值变化时显示出快速且可逆的形状变形。聚伪轮烷与丙烯酸酯的共聚提供了对pH和离子强度敏感的混合4D打印材料。
