Abstract
The change in optical transmittivity of the nematic-aerogel system in an alternating external electric field was investigated near the nemat ic-isotropic phase transition. We observed a slow, glasslike dynamical reorientation process that is probably correlated over many pores. Th e magnitude of the change in the transmittivity can be explained by th e model of Bellini et al.
