    摘要:

    通过超声制备出不同的碳纳米材料分散液。 通过紫外光谱证明分散液中的杂化材料已成功合成,
    同时通过紫外光谱、显微镜扫描和沉淀实验表征碳纳米材料的分散性。 结果表明:相比于碳纳米管和石墨烯,碳
    纳米管/ 石墨烯杂化材料皆具有优异的分散性,但由于杂化材料合成机理的差异,在一步法制备杂化材料中碳纳
    米管和石墨烯有相同机会和聚丙烯酰氯发生反应,可更好地阻碍碳纳米管的团聚,因此一步法合成的碳纳米管/
    石墨烯杂化材料的分散性要优于多步法合成的杂化材料,实现了碳纳米杂化材料分散性的优化。

    Abstract:

    The suspensions were prepared with different carbon nanomaterials. The UV spectrum proved that the
    hybrid materials were prepared successful. The dispersion of suspensions was characterized by the UV spectrum, opti-
    cal microscopy and sedimentation tests. The results showed that hybrid materials both have the excellent dispersion as
    well. However, due to the difference of synthesis mechanism, the dispersion of hybrid materials (one step) were bet-
    ter than the hybrid materials (multi-step) owing to the PACl which had the same opportunity to react with GnPs-OH
    and MWCNTs- OH to hinder the aggregation of MWCNTs-OH. So the aiming of optimization of dispersion for carbon
    nanomaterials was achieved.
