Switchable Tackiness andWettability of a Liquid Crystalline Polymer

Guillaume de Crevoisier1 , Pascale Fabrel , Jean-Marc Corpart2 , Ludwik Leibler1

The spreading velocity of liquids on the surface of a liquid crystalline polymer can be tremendously affected by a slight temperature change. Indeed, a bulk transition between a highly ordered smectic and an isotropic phase induces a sharp change from a rigid to a soft behavior, with consequent effects on the tack properties of the liquid crystalline polymer and on the dewetting dynamics of a liquid on its surface.
