Kl. Sandhya et al., Dynamics of the two-dimensional melting transition of a liquid crystal confined in Anopore membranes, LIQ CRYST, 28(12), 2001, pp. 1847-1853
Dielectric measurements on a liquid crystal exhibiting the smectic A-crysta
l B transition and confined to Anopore membranes having 20 and 200 nm pore
sizes are reported. The studies reveal that compared with the bulk, the con
fined material shows a decrease in transition temperature. More importantly
, the confinement leads to a slowing of the relaxation mechanism by about t
hree orders of magnitude.
