Abstract

Repeatedly forming temporary shapes limits the employment of shape-memory polymers. T. J. White and co-workers use glassy, liquid crystal polymer networks to spontaneously form 3D shapes that are independent of an agent. On page 2839 they show how these shapes can be autonomously fixed with rapid temperature cycling. In the image, a spiral ribbon shape has been imaged after dipping into a chemilumines-cent solvent for increased contrast.
