The 4D-printable two-way shape memory effect (TWSME) is not well known to building engineering and architecture. To better understand the thermo-mechanical complexity of TWSME in skin design, this paper investigates parametric uncertainty basic deformation a rectangular façade surface module. end, 4D-printed composite was prototyped by 3D-printing polymer (SMP, digital elastomers DM9850 9885) d...

Poly N-isopropylacrylamide was successfully grafted onto a polystyrene cell culture dish by gamma ray. In this study, the effect of a radiation dose (radiation absorbed dosages of 10, 20, 30, 40 KGy) under appropriate temperature and grafting conditions was investigated. The FTIR analysis showed the existence of the graft PNIPAAm on the substrate. The optimal value of the dose for grafting was ...

Topological metamorphosis represents a powerful approach to modulate the properties of polymers. However, it still remains major challenge achieve tunability bulk mechanical via topological transformation in supramolecular polymer systems. Herein, we couple covalent and single system—referred as covalent-and-supramolecular (CSP)—to realize thermo-responsive macromolecular metamorphosis. The CSP...
