초록
타이타늄산바륨(BaTiO3)은 대표적인 강유전 물질로 유전상수가 200 이상의 값을 나타내는 물질이다. 타이타늄산바륨을 나노입자화하면 나노커패시터(nanocapacitors)와 강유전체 메모리(ferroelectric random access memories)와같이 여러 용도로 응용 가능하다. 하지만, 나노입자의 합성방법에 따라 나노입자의 분산특성이 달라지며 이에 활용할 수있는 분야가 달라질 수 있다. 본 연구에서는 타이타늄산바륨 나노입자를 옥살레이트법(oxalate method)과 sol-gel법(ambient condition sol method)으로 합성하고 각 방법에 따른 나노입자의 크기와 분산상태를 확인하였다. 각각의 공정에사용한 캡핑 에이전트(capping agent)는 poly vinyl pyrrolidone (PVP)을 옥살레이트법에 이용하였고 sol-gel법에는tetrabutylammonium hydroxide (TBAH)를 이용하였다. 합성된 나노입자의 X-선 회절 분석 패턴을 분석하여 cubic 결정구조를 갖는 타이타늄산바륨을 확인하였다. 푸리에(Fourier) 변환 적외선 분광분석을 이용하여 나노입자의 캡핑 에이전트 결합상태와 시차주사현미경과 입도분석기를 이용한 나노입자의 크기 및 뭉침 변화를 확인하였다.
Abstract
BaTiO3 is typical ferromagnetic materials with dielectric constant of above 200. BaTiO3 nanoparticles applications are available for multiple purposes such as nanocapacitors, ferroelectric random access memories, and so on. Applications are is diverse from the dispersion of nanoparticles depending on the route of synthesis. In this study, BaTiO3 nanoparticles were synthesized by two different methods such as oxalate method and sol-gel process (ambient condition sol method). Particle size and dispersion condition were studied according to the preparation method and capping agent. Poly vinyl pyrrolidone (PVP) was used as a capping agent in oxalate method and tetrabutylammonium hydroxide (TBAH) used as a capping agent in sol-gel process each. Cubic crystal structure of BaTiO3 phase could be confirmed by X-ray diffraction analysis. Fourier transform-infrared spectroscopy was employed for the confirmation of the capping agent and BaTiO3 nanoparticles. The particle size and distribution analysis was also performed by particles size analyzer and scanning electron microscope.
