Bending and Stretching Actuation of Soft Materials through Surface‐Initiated Polymerization

Abstract

A redhead: Surface-grafted hydrophilic polymer brushes (see picture) with high molecular weight and graft density caused reversible bending and stretching of soft polymeric substrates on a macroscale. The shape change of the substrate was tuned to respond to different stimuli including humidity, temperature, and pH.
