광화학증착법에 의한 직접패턴 PZT 박막의 제조 및 특성
박형호,박형호,김태송,Park, Hyeong-Ho,Park, Hyung-Ho,Kim, Tae-Song,Hill, Ross-H. 한국재료학회 2008 한국재료학회지 Vol.18 No.2
The ferroelectric properties of UV irradiated and non-irradiated PZT films prepared via photochemical metal-organic deposition using photosensitive precursors were characterized. Fourier transform infrared spectroscopy showed that complete removal of organic groups was possible through UV exposure of the spin-coated PZT precursor films at room temperature. The measured remnant polarization values of UV-irradiated and non-irradiated PZT films after annealing at $650^{\circ}C$ were 29 and $23\;{\mu}C/cm^2$, respectively. The UV irradiation was found to be effective for the enhancement of the <111> growth orientation and ferroelectric property of PZT film and in the direct patterning in the fabrication of micro-patterned systems without dry etching.

용융탄산염 연료전지에 유용한 저온 저압성형 전해질 matrix를 제조하기 위해 결합제로서 polyethylene을 사용하여 성형온도, 압력, 전해질 조성 및 결합제의 양의 변화가 전해질 matrix 특성에 미치는 영향을 조사하였다. 전해질 matrix의 상온 제조시 최적 성형압력은 150㎏/㎠였으며, 160℃에서는 150㎏/㎠이상의 성형 압력하에서 발생되는 전해질 matrix내 polyethylene의 응집현상과 열응력으로 인해 최적 성형압력은 100㎏/㎠였다. 160℃에서 제조된 전해질 matrix의 강도는 결합제로 첨가된 polyethylene의 영향을 받아 상온 제조시보다 높았다. 또한 상온에서 전해질 matrix의 특성에 가장 큰 영향을 미치는 인자는 전해질 함량이었으며, 160℃에서는 polyethylene의 함량이었다. The electrolyte matrix for MCFC was fabricated by using a polyethylene as a binder under low-temperature and low-pressure. The effects of compaction temperature, pressure, composition of electrolyte matrix and amount of binder on characteristics of electrolyte matrix were investigated in this study. The optimum compaction pressure was 150㎏/㎠ at 25℃, 100㎏/㎠ at 160℃ because of the cluster of polyethylene and thermal stress beyond 150㎏/㎠, respectively. The strength of electrolyte matrix fabricated at 160℃ was higher than that of electrolyte matrix fabricated at 25℃ due to the effect of polyethylene. The most important factor effecting on the characteristics of electrolyte matrix was the amount of electrolyte at 25℃, amount of polyethylene at 160℃ respectively.
