dc.description.abstract Main focus of this study was on characterization of surface properties of virgin and 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) phospholipid layer coated poly(ethylene terephthalate) (PET) and polycarbonate (PC) planar articles. Surface properties were followed measuring static contact angles of wetting by means of sessile drop method and deposition of negative polystyrene (PS) colloidal particles followed by impinging jet method at defined flow regimes. It was found that phospholipid coating of both studied samples (PET, PC) let to the vigorous increase of the surface free energy. For coated samples major part of the surface free energy was dominated by polar component in contrast to the non-treated materials. Here the dispersive component was dominating. Results of the deposition experiments of polystyrene particles of 3 μm diameter correspond with trends obtained by contact angle measurements, i.e. the surface treated materials exhibited higher surface activity reflected in increased particle deposition rates. Simultaneously there was confirmed the fact, that with increasing magnitude of the Reynolds number of the dispersion flux the higher deposition rates were observed. © 2011 Elsevier Ltd.
