Neutron reflectivity and force-balance measurements have been used to study the conformation of block copolymers of polystyrene and poly(2-vinylpyridine) adsorbed on mica, silica and quartz from solution in various solvents. The results are discussed in terms of various theoretical models of the volume fraction profiles of the adsorbed layer. Neutron reflectivity data for polymers adsorbed from solution onto mica, quartz and silica have been obtained. The results show that the reflectivity is sensitive to the structure of the diffuse adsorbed layer. Comparison with theoretical models of the volume fraction profiles of the polymers and with force balance data gives an detailed description of the adsorbed layer.</p
