For nanomesh aluminum films a dependence of the pores parameters on conditions of their fabrication is found. The effect of micropores performances on the minimum width of the aluminum network is shown. The relation between the alignment type and free anchoring energy as well as micropores diameter is derived. The alignment type is influenced by the LC clusters formation and their size. The size of the nematic LC clusters is evaluated. The difference between internal energy of the LC interaction with the micropores surface for both planar and homeotropic orientation is found to be more than two orders lower than the energy of its own value. The mesogen alignment type depends on the difference between entropy values for both planar and homeotropic orientation.

Keywords: mesogen orientation, porous surface, nanoporous films, planar and homeotropic orientation
