Paper Abstract

We describe the formation and selected properties of composites made from DMP-128 transmission holograms and the nematic liquid crystal E7. Analysis of the liquid crystal structure in the composites by polarizing microscopy, refractive index measurements, and differential scanning calorimetry produced two primary observations. (1) Treatment of the interior surface of the porous holograms controls the nature of the liquid crystal alignment; both planar and homeotropic alignment is possible for the E7 composites. (2) Incorporation of E7 into DMP composites significantly reduces its degree of order compared to that for a standard nematic cell.
