Fabrication of Temperature‐Responsive Bending Hydrogels with a Nanostructured Gradient

Abstract

Nanostructured gradient gels with unique bending properties due to their deswelling characteristics are presented. These gradient gels are readily fabricated via electrophoresis followed by photo-polymerization, and subsequent silica extraction. Differences in the physical properties between both sides of the gradient gels are the driving force behind the bending of the gels.
