초록
비수계 용매를 사용하는 폴리올법을 이용하여 여러 반응조건에서 초산니켈 수화물로부터 미세 니켈 분말을 제조하였다. 히드라진 수화물과 polyvinylpyrrolidone (PVP)은 환원제 및 계면활성제로, diethanoamine (DEA)과 triethanolamine (TEA)은 반응 용매로 각각 사용하였다. 반응온도, 비수계 용매 및 계면활성제가 시료의 제조에 미치는 영향을 조사하기 위하여 X-선 회절장치, 주사형 전자현미경, 열분석장치 및 X-선 광선자 분광기 등을 통하여 시료들의 특성을 분석하였다. DEA 및 TEA를 사용한 경우에 PVP의 첨가로 말미암아 니켈 입자들의 응집현상이 효과 적으로 억제되는 것을 확인하였다. DEA를 사용하는 경우에 비하여 TEA를 사용하여 제조된 시료들은 상대적으로 입자 크기가 작고, 입도 분포는 균일하면서, 표면이 매끈하였다.
Nickel powders were prepared from nickel acetate hydrate at various reaction conditions using non-aqueous solution in the polyol method. Hydrazine and polyvinylpyrrolidone (PVP) were used as the reducing agent and the surface activator, respectively. Diethanolamine (DEA) and triethanolamine (TEA) were used as the non-aqueous solvent. To investigate the effect of reaction temperature, non-aqueous solution and surface activator in the preparation of samples, the characteristics of samples were analyzed by means of X-ray diffractometry, Scanning electron microscopy, thermal gravimetry, and X-ray photoelectron spectroscopy. It was found that the agglomeration of nickel particles was effectively prevented by the addition of PVP in both cases using DEA and TEA. Compared to the case of using DEA, smaller particle size, more uniform size distribution and more smooth surface were obtained in the samples prepared using TEA.
