Contact angle between smectic film and its meniscus

Author(s): Poniewierski, A and Oswald, P and Holyst, R
Title: Contact angle between smectic film and its meniscus
Abstract: We apply de Gennes model (Langmuir, 1990, 6, 1448-1450) for presmectic to a freely suspended smectic film coupled to the meniscus. We that the quartic term in the expansion of the free energy in power the smectic order parameter cannot be neglected in the model in order explain the full behavior of the contact angle, theta(m), between the and the meniscus. As shown previously (Phys. Rev. E 2001, 63, this contact angle is nonzero due to the disjoining caused by the enhanced smectic ordering at the film surfaces. temperature dependence of theta(m) with a maximum above the bulk of the nematic-smectic phase transition, T-NA, is
