Description
An atomic force microscope, modified to perform dynamic measurements, has been used to measure the lubrication forces between a colloid probe and flat substrate in the normal direction. The hydrodynamic interactions were measured for bare surfaces and for surfaces with an adsorbed layer of the weak polyelectrolyte, poly(2-vinylpyridine) in aqueous solution. The flow of liquid between the surfaces is described in terms of the effective mobility, G. At surface separations far exceeding twice the...[Show more]
