Equation of State for Columnar Liquid Crystals

With a consideration of the local lateral freedom of molecules, a general equation of state for columnar liquid crystals is derived, which is in agreement with the one obtained by Wensink [ 1 ] in the density limit. It is also shown that an additional negative pressure, which is not negligible, tend...

Summary:With a consideration of the local lateral freedom of molecules, a general equation of state for columnar liquid crystals is derived, which is in agreement with the one obtained by Wensink [ 1 ] in the density limit. It is also shown that an additional negative pressure, which is not negligible, tends to be generated for thick disc-like liquid-crystalline molecules even in a high-density regime because of the cavities they create as a result of the allowed lateral motion.
