[Paper] Stabilization Effect of Self-Assembly Dendrimer Doped Cholesteric Liquid Crystal on Helical Structure

Abstract

In this paper, we report the resettable functionality of helix pitch length in the mixture composed of cholesteric liquid crystal and self-assembly dendrimer with lysine groups. Cholesteric-phase liquid crystal was obtained by doping a tiny amount of dendrimer less than 0.01 wt% concentration. The mixture showed not only thermal stability of helix pitch length but also resettability of that by temperature control process based on sol-gel transition characteristics in the dendrimer with lysine group. We discuss the temperature effect of the proposed cholesteric liquid crystal on such unique functionality.
