Impinging Jet Study of the Deposition of Colloidal Particles on Modified Polycarbonate and Poly(Ethylene Terephthalate) Surfaces

Popis výsledku v původním jazyce

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 propertieswere 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 ofboth 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 wasdominating. Results of the deposition experiments of polystyrene particles of 3 mu m diameter correspond with trends obtained by contact angle measurements, i.e. the surface treated materials exhibited higher surface activity reflected in
