N2 - We have studied the effect of the rubbing fabric for pretilt angle generation, polar anchoring strength (energy), and the surface order parameter in nematic liquid crystals (NLC), 4-cyano-4′-n-penthylbiphenyl (5CB), on rubbed polyimide (PI) surfaces. The pretilt angle of 5CB for nylon and rayon fabric is larger than that of cotton fabric in weak rubbing on rubbed PI surfaces. The polar anchoring energy and surface order parameter of 5CB for nylon fabric are larger than those of cotton fabric on rubbed PI surfaces. We suggest that the polar anchoring energy and surface order parameter of 5CB increase with hard rubbing fabric. Finally, we conclude that the polar anchoring energy of 5CB is strongly related to the surface order parameter on rubbed PI surfaces.
