摘要：

The high molecular dielectric dipole moment of doping material is promising, to improve the electrorholegical (ER) effect. It is found that triethanolamine (the molecular dipole moment of triethanolamine is 3,48)-modified TiO2 has good ER properties. Under 5 kV/mm external electric field. the yield stress is 32.6 kPa, which is about 50 times higher than that of TiO2 and the leaking electric current density is lower than 16 mu A/cm(3). The sedimentation rate is about 98% in 20 days. (C), 2006 Elsevier Inc. All rights reserved.
