Light‐Fueled In‐Operando Shape Reconfiguration, Fixation, and Recovery of Magnetically Actuated Microtextured Covalent Adaptable Networks

open access: yesAdvanced Materials, EarlyView.
A covalent adaptable network with dynamic disulfide bonds (DS‐CAN) can rearrange its molecular topology through heating or UV irradiation. When combined with ferromagnetic particles, its photoresponsiveness at room temperature enables contactless, spatiotemporal regulation of dynamic bond exchanges during magnetomechanical actuation.
