Director distributions of nematic liquid crystals in hybrid arrangement cylindrical cells
摘要
Abstract
By using nematic liquid crystal elastic theory,we study the director distributions of nematic liquid crystal in hybrid arrangement cylindrical cells.Nematic liquid crystal is restricted in two concen-tric cylindrical layers,inside and outside surface application strong anchoring and weak anchoring boundary condition,anchor set to boundary conditions of the radial and axial direction(vertical and parallel axis),obtaining four models ZsRw,ZwRs,RsZw and RwZs.Based on the Frank elastic free energy and the Rapini Papoular approximation to the surface anchoring strength,we obtain the direc-tor distributions with antagonistic anchoring conditions, different radius and different elastic constants.We calculate and simulate the director orientation graph.Because of the influence of column symmetry,anchoring strength,layer thickness and elastic anisotropy,the director distributions of these four models are very different.关键词
