We studied the formation mechanism of dendritic fibrous nanosilica (DFNS) that involves several intriguing dynamical steps. Through electron microscopy and real-time small-angle X-ray scattering studies, it has been demonstrated that the structural evolution of bicontinuous microemulsion droplets (BMDs) and their subsequent coalescence, yielding nanoreactor template, is responsible for to the formation of complex DFNS morphology. The role of cosurfactant has been found to be quite crucial, which allowed the understanding of this intricate mechanism involving the complex interplay of self-assembly, dynamics of BMDs formation, and coalescence. The role of BMDs in formation of DFNS has not been reported so far and the present work allows a deeper molecular-level understanding of DFNS formation.

阐明树状纤维纳米二氧化硅的形成机理

我们研究了树枝状纤维纳米二氧化硅（DFNS）的形成机理，其中涉及几个有趣的动力学步骤。通过电子显微镜和实时小角X射线散射研究，已证明双连续微乳液液滴（BMD）的结构演变及其随后的聚结，产生纳米反应器模板，是造成复杂DFNS形态的原因。 。已经发现助表面活性剂的作用非常关键，这使人们对这种复杂的机制的理解成为可能，其中涉及到自组装，BMDs形成的动力学和聚结的复杂相互作用。迄今为止，尚未报道BMD在DFNS形成中的作用，目前的工作使人们对DFNS形成有了更深入的分子水平的了解。
