Abstract

We have demonstrated that ubiquitous van der Waals forces are significant in controlling the interactions between nanoparticles and nanotubes. The adsorption of gold nanoparticles (AuNPs) on nanotubes (MWNTs) obeys a simple quadratic dependence on the nanotube surface area, regardless of the source of AuNPs and MWNTs. Changes in the geometric parameters of the components have pronounced effects on the affinity of nanoparticles for nanotubes, with larger, more polarizable nanostructures exhibiting stronger attractive interactions, the impact of which changes in the following order MWNT diameter > AuNP diameter > MWNT length.

摘要

我们已经证明，普遍存在的范德华力在控制纳米粒子和纳米管之间的相互作用方面非常重要。金纳米粒子（AuNPs）在纳米管（MWNTs）上的吸附与纳米管表面积呈简单的二次依赖关系，而与 AuNPs 和 MWNTs 的来源无关。组成部分的几何参数的变化对纳米粒子与纳米管的亲和力有显著影响，较大的、更可极化的纳米结构表现出更强的吸引力相互作用，其影响按以下顺序变化：MWNT 直径>AuNP 直径>MWNT 长度。
