Infrared study of the interaction of charged silica particles with TiO2 particles containing adsorbed cationic and anionic polyelectrolytes.


Attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopy was used to study the adsorption of charged silica particles onto TiO(2) particles coated with anionic sodium polyacrylate (NaPA) or cationic poly(diallyldimethylammonium) chloride (PDADMAC). To the best of our knowledge, this is the first time that IR spectroscopy has been used… (More)
