Abstract
Shear induced adsorption/desorption of a highly entangled polymer melt from an attractive interface was directly observed using neutron reflectometry. The concentration of poly(methyl methacrylate) (d-PMMA) in a hydrogenated PMMA matrix was measured within 20 {Angstroms} of the surface of silicon wafers after an applied shear deformation. Substantial decreases in the surface concentration of d-PMMA relative to that in the static case were observed with increasing shear rates.
