Study on Surface Modification of Nano-Alumina with Silicane Coupling Agent KH550

Abstract:

Silane coupling agent KH550 was used to modify the surface of nano-alumina. Ultrasonic dispersion was employed to take the place of traditional mechanical stir. Absorbency of the aqueous solution of nano-Al2O3, which had been modified, was determined to confirm that under this process condition the optimum amount of KH550 was 2.5% while the optimum time was 50 minutes. The infrared spectra indicated that the surface of nano-Al2O3 had been modified and the absorption of KH550 really existed there.
