Abstract

We demonstrate a new method to fabricate a large-area polymer gravel array. The formation of the polymer gravel array on the substrates of the liquid crystal (LC) cell during polymerization is attributed to the surface tension interaction among the LC, prepolymer, and substrate surface. The gravel can be oriented along the rubbing direction of the substrate. Moreover, the diameter and pitch of the oriented gravel array can be controlled by means of UV curing intensity and supplied voltage under curing because of the competition between the dipole and quadrupole interactions of the colloidal prepolymer droplets. The estimated anchoring energy given by the oriented polymer gravel array can align LCs. The possible application of the formed periodical gravel array on optical devices is explained in this paper.
