A study of the adsorption of several surfactants onto lead zirconate titanate (PZT) powder was performed. The adsorption of oleyl alcohol, steryl alcohol, oleic acid, and stearic acid onto PZT-5H powder (surface area = 2.58m2/g) was measured by thermogravimetric analysis. Tolune was used as a solvent, and the solution concentrations were set at 50.0 g/L. It was found that the stearic acid adsorption onto the PZT-5H powder was highest, to the extent of 8.1 mg/m2. Trace amounts of stearyl alcohol adsorbed onto PZT, showing an adsorption of 0.8 mg/m2. Both oleyl alcohol and oleic acid showed no measurable adsorption.
