  • 摘要: 以多壁碳纳米管（multi-walled carbon nanotubes， MWNTs）为对象，研究不同分子量分布区间天然有机物（natural organic matter， NOM）和电解质对MWNTs在水中凝聚及分散行为的影响.结果表明，低分子量（100 k Da）NOM可强化凝聚发生.不同分子量区间NOM将通过不同机制影响碳纳米材料在水中的凝聚.
    Abstract: Effects of natural organic matter (NOM) with different molecular weight and electrolytes on the aggregation and dispersion of multi-walled carbon nanotubes (MWNTs) were investigated. The results showed that low molecular weight NOM (100 k Da) promoted the aggregation of MWNTs with high concentration electrolyte. NOM with different molecular weight could influence the aggregation of carbon nanomaterials through different mechanisms in aquatic systems.
