Abstract
The infrared spectra of the additives adsorbed on nano-zirconia powder surfaces were measured by using diffuse reflectance Fourier transform (DRIFT) spectroscopy. The nature of the structural information has been studied by preparing zirconia suspensions at various pH and different concentrations of polyacrylate addition. These DRIFT spectra can provide useful information about polyacrylate existence on zirconia surface including the ionization degree and its configuration. The addition of polyacrylate into zirconia aqueous suspension could completely change the surface chemistry and interaction of zirconia particles.
