Abstract
The surface composition of model polymers and surface-treated polycarbonate membranes has been investigated by X-ray photoelectron spectroscopy. Information on functional groups present on the surface, deduced from the position or decomposition of the C1s, N1s and S2p peaks, may be confirmed and sometimes extended by comparing these data with the elemental composition deduced from the intensity of the various peaks observed. The surface energy of the samples has been computed from contact angle measurements. A good correlation was found between the polar contribution of the surface energy γs p and the mole fraction of oxygen carrying a high electron density, as determined by considering the 01s components with a binding energy at or below 533.4 eV. The surface functionality and the relationship between surface energy and surface chemical composition are key factors for understanding and controlling the attachment and spreading of animal cells.
