| 摘 要： | 以分子量为600、400和200的聚乙二醇（PEG）为介质电弧放电法制备了洋葱状富勒烯（OLFs）；利用空气氧化法于450℃条件下对产物进行了提纯，并用含氧射频等离子体对纯化后的OLFs进行了表面氧化修饰；用场发射扫描电镜、高分辨透射电镜、X射线衍射和傅立叶变换红外光谱对所得产物进行了表征和分析。结果表明：在PEG200中放电制得的OLFs粒径均匀，石墨化程度较高；空气氧化法能提高OLFs产物的纯度；当氧气含量为20％时，表面氧化修饰效果明显。

| Abstract: | Onion-like fullerenes(OLFs) were synthesized by arc-discharge in polyethylene glycol(PEG) liquid with different molecular weight(600,400,200).The as-synthesized products were purified by air oxidation.Then purified OLFs were modified with surface oxidation in oxygen-containing radio frequency(RF) plasma.The morphologies and structures of the products were characterized by field emission scanning electron microscopy,high resolution transmission electron microscopy,X-ray diffraction and Fourier transform infr... |
