Description
Molecular dynamics (MD) simulation was performed for 4-octyl-4'-cyanobiphenyl (8CB) liquid crystalline free-standing film (FSF) in order to understand its formation mechanism and structure. The free-standing film was successfully reproduced by MD simulation using the ordinary pairwise atom-atom potential parameters without any phenomenological constraints, therefore the free-standing film was concluded to be stabilized mainly by the intermolecular interaction between the liquid crystalline molecules. The simulation also provided preliminary information on phase transition temperatures, orientational order parameter, layer spacing and film thickness. The free-standing film showed the SmA phase in a higher and wider temperature range than the bulk. This result agrees with the transmission ellipsometry measurement for an analogue liquid crystal
