Geometry‐Dependent Adhesion in Transparent Monodomain Liquid Crystal Elastomers
Advanced Functional Materials, EarlyView.Liquid Crystal Elastomers (LCEs) are emerging as exciting pressure‐sensitive adhesives. We examine adhesion in chemically identical elastomer films, exploring the influence of geometry (director orientation) and phase (nematic or isotropic). We demonstrate the potential of these aligned films as transparent, tunable, broad‐temperature‐range smart ...
