dc.description.abstract | Static force-distance relations as well as linear and nonlinear viscoelastic responses to oscillatory shear were studied in 4'-n-pentyl-4-cyanobiphenyl (5CB) confined between two muscovite mica surfaces at 25 degreesC. The orientation of the crystallographic axes of the mica sheets was varied from close to perfect alignment to a twist angle of theta > 80 degrees, and the sliding direction was kept parallel to the gamma optical axis of one mica sheet. The layering was unaffected by twist angle when the film thickness exceeded three molecular layers of 5CB in a planar orientation, but for two and three layers the adhesive minima in the oscillatory force-distance curve decreased in magnitude with increasing theta. In the linear viscoelastic response (obtained with shear deformations of <20% of the film thickness), an elastic response dominated at shear frequencies of 0.13-130 Hz and small |
