A reliable explanation for the underlying mechanism responsible for the persistent aggregation and self-assembly of colloidal 5 nm diamond nanoparticles is critical to the development of nanodiamond-based technologies. Although a number of mechanisms have been proposed, validation has been hindered by the inherent difficulty associated with the identification and characterisation of the inter-particle interfaces. In this paper we present results of high resolution aberration corrected electron microscopy and complementary computer simulations to explicate the features involved, and confirm the electrostatic interaction mechanism as the most probable cause for the formation of agglutinates and agglomerates of primary particles.
对于导致胶体 5nm 金刚石纳米颗粒持续聚集和自组装的潜在机制，给出一个可靠的解释，对于发展基于纳米金刚石的技术至关重要。尽管已经提出了许多机制，但由于与颗粒间界面的识别和特性相关的固有困难，验证受到了阻碍。在本文中，我们通过高分辨率像差校正电子显微镜和互补的计算机模拟结果来阐述相关特征，并证实静电相互作用机制是初级颗粒团聚体和聚集体形成的最可能原因。
