Fig. 1: Fabrication and actuation of shape-morphing particles.

A PDEAM-BP is a stimuli-responsive swellable hydrogel, and PpMS-BP is a glassy polymer. B Schematic representation illustrating fabrication of shape-morphing particles from a bilayer of PpMS-BP (rigid layer) and PDEAM-BP (swelling layer) by UV-crosslinking and developing. C Bending curvature of a shape-morphing particle (black circles) and linear swelling ratio of PDEAM-BP, defined as the ratio in diameter of a PDEAM-BP sample compared to that in its dry state (blue squares), as a function of solution temperature. Data points represent mean values, and error bars indicate mean ± SD (n  =  5). D Fluorescent microscope images showing reversible bending of a bilayer particle upon decreasing temperature across VPTT.
