Mm. Marugan et al., SUPERMOLECULAR ALIGNMENT IN A LIQUID-CRYSTAL POLYMER GEL AS STUDIED OPTICALLY AND BY DIELECTRIC-RELAXATION SPECTROSCOPY, Journal of materials chemistry, 6(4), 1996, pp. 667-669
Macroscopically aligned liquid crystal(LC) gels have been prepared by
photopolymerization in visible light of a nonmesogenic bifunctional mo
nomer in a conventional LC mixture that was prealigned in an electric
field. A high degree of molecular orientation is achieved in the gel,
and it is stable with time, as shown by polarized optical microscopy a
nd broad-band dielectric relaxation spectroscopy.
