摘要
以SDS／正戊醇／二甲苯／H2O微乳液为对象，考察了体系含水量与分散相和水核半径的关系，以及制备条件对纳米镍颗粒大小的影响。TEM、选区电子衍射和XRD对纳米镍进行了表征，结果表明，水核半径和体系含水量之间存在着线性关系，分散相和水核半径，分散相中表面活性剂分子随着含水量的增加而变大。
The structural parameters of microemulsion and preparation of nano-nickel by microemulsion were studied. The effects of H2O amount and dispersion phase on the radius of inner water droplet, and the effects of technique to prepare nano-Ni particle on the particle size were investigated for the microemulsion of sodium dodeeyl sulfate （SDS） / n- pentanol / Xylene / H2O. The samples of nano-Ni were characterized by X-ray powder diffraction （XRD）, transmission electron microscop （TEM） , corresponding selected area electron diffraction （SAED）. It was shown that there was the linear relationships between the radius of inner water droplet and H2O amount of the system.
