摘要：

The incorporation of 38 nm titanium dioxide nanoparticles into an epoxy matrix to form a nanocomposite structure is described. The practical use of such materials has been evaluated through careful measurements of their electric strength made using recessed specimens as a function of particulate loading in comparison with an equivalent conventional resin formulated with micro-scale TiO2 filler. The results would suggest that significant advantages accrue from the nano-formulated material in keeping with the known reduction in internal space charge accumulation earlier determined by pulse electroacoustic measurements. Furthermore, it is demonstrated that an optimum loading is indicated at about 10% (by weight). Based on additional thermally stimulated current and electroluminescence data, some suggestions are advanced which explain the improved performance in terms of the mitigating effects of trapped entanglement on the Maxwell-Wagner effect.
