Improvement in holographically formed polymer-dispersed liquid crystal performance through acrylated monomer functionality studies
Proceedings of SPIE, v 3800(1)
14 Oct 1999
Abstract
We investigate the effect of monomer blends on the performance of holographically-formed polymer dispersed liquid crystals (H-PDLCs). Difunctional, trifunctional, and hexafunctional urethane acrylate resins are mixed in different ratios to yield monomers characterized by an effective functionality. Reflection H-PDLCs are formed using the different blends. Reflection efficiency and voltage response are measured. Monomer blends prepared with trifunctional/hexafunctional constituents are formed to yield H-PDLCs with higher reflection efficiency than their difunctional/hexafunctional counterparts, but require higher voltages to switch. Scanning electron microscope investigations are also undertaken.
