Popis: | 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 TiO 2 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 pure TiO 2 and the leaking electric current density is lower than 16 μA/cm 2 . The sedimentation rate is about 98% in 20 days. |
