摘要	The quantitative adsorption behavior of a hyperdispersant onto nano-TiO2 particles has been characterized by using FTIR (Fourier transform infrared) spectroscopy, NMR (nuclear magnetic resonance) and a negative adsorption method. The intrinsic adsorbed amount of hyperdispersant was (1.05+/-0.09) mg/m(2). Thickness of the adsorbed layer was (4.66+/-0.42) nm. There was (74+/-7)% wt water in the adsorbed layer. In the hyperdispersant molecule, the anchoring group of the amide group attached firmly to the nano-TiO2 particles, and the solvatable chains of comb-type structure exhibited the effective steric stabilization.
