文摘

The synthesis and characterization of several mesogenic antiferroelectric gels-obtainedby in situ photopolymerization of mixtures of a nonchiral diacrylate and a nonreactivecompound with an antiferroelectric SmC*_A phase-is described. Along with kinetic aspectsfrom their photopolymerization processes, information has been obtained concerning thedielectric permittivity, spontaneous polarization, optical response to an applied electric field,and the influence that the photopolymerization conditions and the structural characteristicsof the network have on these properties. We have found that the polymer network not onlystabilizes the antiferroelectric orientation but also alters the electro-optic properties of theliquid crystal.
