Polar and azimuthal anchoring energy of liquid crystals

Abstract

The interaction energy between mesogenic molecules (diphenyl, pentylbiphenyl and 4-n-octyl-4′-cyanebiphanyl) and the graphite and PE surface has been calculated using atom-atom potentials method. Polar and azimuthal anchoring energies are obtained and their dependences on the order parameter were derived. The good coincidence of calculated values of anchoring energies as well as of their dependences on the order parameter with experimental data is shown
