摘要：

Crystalline oriented titania (anatase) thick films have been fabricated by electrophoretic deposition in a strong 12T magnetic field. Anatase particles in an aqueous suspension are rotated due to their magnetic anisotropy and then deposited on a substrate in a dc electric field. The angle between the directions of the magnetic and electric fields phi(B-E) is fixed at specified angles (phi(B-E) = 0, M 60 and 90 degrees) during the deposition to control the dominant crystalline orientation of the deposits. The crystalline orientation characterized by the X-ray diffraction for the anatase films proves the orientation dependence of anatase upon the phi(B-E) angle during the EPD. The crystalline orientation of the anatase films can be controlled by varying the angle of E versus B. (c) 2005 Elsevier Ltd. All rights reserved.
