Chain flattening and infrared dichroism of adsorbed poly(ethylene oxide)

The adsorption of poly(ethylene oxide), PEO, from dilute solutions in 1 mM aqueous NaCl to germanium at 30°C, was investigated by polarized infrared spectroscopy in attenuated total internal reflection (ATR). PEO aggregation could be prevented with careful sample preparation. After adsorption, chain...

Description
Summary:The adsorption of poly(ethylene oxide), PEO, from dilute solutions in 1 mM aqueous NaCl to germanium at 30°C, was investigated by polarized infrared spectroscopy in attenuated total internal reflection (ATR). PEO aggregation could be prevented with careful sample preparation. After adsorption, chain anisotropy was deduced from the COC stretching vibrations along the polymer backbone and found to indicate substantial backbone alignment parallel to the surface.
