Tunable wrinkling of thin liquid crystal elastomer membranes

nlce

We study the formation of wrinkles due to compressive stress of a thin nematic liquid crystal elastomer atop an elastic or fluid substrate. Using a Foppl-von Karman-like plate theory for the nematic elastomer, we find the scaling of wrinkle wavelength and amplitude in terms of material parameters and the applied compression. The result is that unlike in thin isotropic elastomer films, the number of wrinkles is a non-monotonic function of strain and material parameters. Furthermore, there are multiple ways to suppress wrinkling by tuning the nematic-rubber coupling parameters.
