POLYMERS AS SURFACE MODIFIERS FOR PREPARATION OF CoPt_3 NANOPARTICLE MONOLAYER FILMS

摘要

To fabricate a well-ordered monolayer of CoPt_3 nanoparticles that covers large areas a spin coating technique was used. Prior to particle deposition poly(vinyl pyridine) (PVP) and poly(ethylen oxide) (PEO) were used as surface modifiers of oxidized silicon wafers. Grazing incidence small-angle X-ray scattering, atomic force and electron scanning microscopy were used to characterize the polymer and particle layers and to study the influence of polymers as substrate modifiers on the particle packing.
