Abstract
An adsorption-induced anchoring transition was found by confining liquid-crystal hydrophobic aerosil dispersions to cylindrical pores. The aerosil effects on the director configurations and on the orientational-order wetting at the pore walls were determined by DNMR. The aerosil spheres are adsorbed at the pore wall, hindering the planar anchoring and inducing an axial-to-radial structural transition dependent on increasing aerosil density. The orientational-order surface wetting in the isotropic phase is modified by the aerosil-introduced disorder from quasi-complete to partial to non-wetting.
