Abstract

Nanocomposite means that the size of the second particles dispersed in the matrix is nanometer order. It was reported that this nanocompostie shows particular properties, different from a general composite in which the second particles are usually micrometer-order. Especially, mechanical properties were known to be enhanced largely. However, there is little report about how electroceramic properties are changed by making nanocomposite. Thus, in this research, we made PNN-PZT/Ag nanocomposite by hot-pressing method, and microscopic and dielectric properties are studied.

나노 복합체는 제 2상의 크기가 나노 사이즈인 복합체를 의미한다. 이러한 복합체는 제 2상이 마이크론 사이즈인 경우와 다른 독특한 특성을 나타내는 것으로 보고되며, 특별히 기계적 특성이 많이 향상되는 것으로 보고되고 있다. 하지만 이러한 나노 복합체가 전자세라믹 재료의 특성을 어떻게 변화시키는지에 대한 연구는 아직 미비한 편이다 본 연구에서는 PNN-PZT/Ag나노복합체를 고온 고압 소결법에 의하여 제조하였으며, 미세구조적, 유전적 특성에 대하여 고찰하였다.
