| Abstract: | Relationships in variation of the surface energy of polystyrene coatings on melted quartz at varied polymer concentration in solution were refined by studying the functional chemical composition and surface structure of model coatings of atactic polystyrene on quartz plates and the electromigration properties of capillary columns with polystyrene coatings. The optimum concentration and temperature-kinetic conditions for preparing polystyrene coatings on quartz capillaries with controllable electrokinetic properties were determined. |
