Abstract

The crucial roles of the ionization state and counterion presence on the phase behavior of fatty acid in aqueous solutions are well-established. However, the effects of counterions on the adsorption and morphological state of fatty acid on nanoparticle surfaces are largely unknown. This knowledge gap exists due to the high complexity of the interactions between nanoparticles, counterions, and fatty acid molecules in aqueous solution. In this study, we use adsorption isotherms, small angle neutron scattering, and all-atom molecular dynamic simulations to investigate the effect of addition of ethanolamine as a counterion on the adsorption and self-assembly of decanoic acid onto aminopropyl-modified silica nanoparticles. We show that the morphology of the fatty acid assemblies on silica nanoparticles changes from discrete surface patches to a continuous bilayer by increasing concentration of the counterion. This morphological behavior of fatty acid on the oppositely charged nanoparticle surface alters the interfacial activity of the fatty acid-nanoparticle complex and thus governs the stability of the foam formed by the mixture. Our study provides new insights into the structure-property relationship of fatty acid-nanoparticle complexes and outlines a framework to program the stability of foams formed by mixtures of nanoparticles and amphiphiles.

摘要

脂肪酸在水溶液中的离解状态和抗衡离子存在对其相行为的至关重要作用已经得到了充分证实。然而，抗衡离子对脂肪酸在纳米粒子表面的吸附和形态状态的影响在很大程度上尚不清楚。由于纳米粒子、抗衡离子和脂肪酸分子在水溶液中的相互作用非常复杂，因此存在这种知识差距。在这项研究中，我们使用吸附等温线、小角中子散射和全原子分子动力学模拟来研究添加乙醇胺作为抗衡离子对癸酸吸附和自组装到氨丙基修饰的硅纳米粒子上的影响。我们表明，通过增加抗衡离子的浓度，脂肪酸在硅纳米粒子上的组装形态从离散的表面斑块变为连续的双层。这种脂肪酸在带相反电荷的纳米粒子表面上的形态行为改变了脂肪酸-纳米粒子复合物的界面活性，从而控制了由混合物形成的泡沫的稳定性。我们的研究为脂肪酸-纳米粒子复合物的结构-性能关系提供了新的见解，并为通过纳米粒子和两亲物混合物形成的泡沫的稳定性提供了一个框架。
