Influence of alkyldiacrylate side-chains on electro-optical properties in liquid crystal/composite films

摘要

In order realize a paper-like display using polymer-network liquid-crystal (PNLC) films, an increase in backscattering intensity is required. The morphology of the films, and the molecular interactions between the liquid crystals and polymers forming the polymer network, both play an important role in determining film electro-optical properties such as the driving voltage and the reflectance. We have analyzed several factors related to the morphology of the films. Aiming at a reduction in the driving voltage, the effects of alkyl side-chains in diacrylates have been investigated. Based on the results, we successfully produced a prototype paper-like display.
