Abstract

We studied highly anisotropic periodic structure formed by liquid crystal and polymer phase separation, or holographic polymer dispersed liquid crystal (HPDLC), by θ−2θ optical diffractometry particularly employing the high order Bragg diffractions. Then, we revealed the relationship between microscopic structure and diffraction properties of the HPDLCs prepared at several different conditions with regard to the compositional ratio of the raw materials and the exposure temperature. The high order Bragg diffractions are closely connected to periodic boundaries between LC droplets and polymer, and is potentially able to be designed by HPDLC fabrication processes. The analysis with the information from the higher order Bragg diffraction is expected to allow you to observe more detailed and quantitative HPDLC internal structure.
