Rotational Solid Friction of a Nematic Liquid Crystal

Résumé

Liquid crystal defects are used as probes to study the local reorientation dynamics of the nematic surface director on SiOx alignment layers. The tracking of the defect's motion reveals the presence of solid friction forces, unexpected in this complex viscous fluid. We identify the director pinning due to a surface quenched disorder as a possible mechanism that gives rise to the measured solid friction.
