We prepared hybrid halloysite nanotubes (HNT/sodium alkanoates) in which the inner cavity of the nanoclay was selectively modified. Physicochemical studies evidenced the interactions between HNT and sodium alkanoates, ruled out clay exfoliation, quantified the amount of the loaded substance, and showed an increase of the total net negative charge, allowing us to obtain rather stable aqueous nanoclay dispersions. These dispersions were exploited as inorganic micelles to capture hydrocarbon and aromatic oils in the vapor and liquid states and were revealed to be nonfoaming but very efficient in encapsulating oils. Here, we have fabricated biocompatibile and low-cost inorganic micelles that can be exploited for industrial applications on a large scale.
我们制备了杂化海泡石纳米管（HNT/ 烷酸钠），其中纳米粘土的内腔被选择性修饰。物理化学研究证明了 HNT 和烷酸钠之间的相互作用，排除了粘土的剥离，定量了负载物质的量，并显示了总净负电荷的增加，这使得我们能够获得相当稳定的水性纳米粘土分散体。这些分散体被用作无机胶束，以捕获气相和液相中的碳氢化合物和芳烃油，并被证明是非泡沫的，但在包封油方面非常有效。在这里，我们制造了生物相容性和低成本的无机胶束，可以大规模应用于工业领域。
