Abstract
A technique for obtaining information on the local chemical surface structure of polymeric materials that involves the chemical force microscopy and X-ray photoelectron spectroscopy methods combined with selective chemical reactions is described. Maps of the force of adhesion of the probe to an area of the surface of a pentane-based plasma-polymerized coating before and after its modification with a selective reagent with an area resolution of 36 nm2 are plotted. The adhesion force changes in the range 3.2–7.4 nN. It has been established that hydroxyl groups on the studied surface are located predominantly along topographic folds on the film surface.
