Abstract

Nanoscience has grown in recent decades since the development of nanoparticle synthesis and application. Although many studies have phenomenologically interpreted the formation of particles at the nanometric scale, the evolution of this field of study has focused on controlling the parameters enabling the attainment of desired morphologies and dimensions using ligands on nanoparticle surfaces. Molecules bound to nanostructured surfaces act in morphological control and aggregation processes as surface ligands transfer functional characteristics to nanostructures, which show core differences from that class of material. This study shows recent advances in nanoparticle surface functionalization with ligands either in their synthesis or in subsequent steps to modify nanoparticle surfaces. We also offer a discussion on ligand classification based on Lewis acid‒base properties and their impact on the colloidal stability of nanoparticles, enabling us to analyze the solvent‒ligand interactions that transfer characteristics from the ligand to the nanoparticle, generating flocculated or dispersed colloidal solutions.

纳米结构表面的功能化:从对合成过程中形态控制的影响到对胶体分散的影响
自纳米粒子的合成和应用发展以来,纳米科学在近几十年中不断发展。尽管许多研究都从现象上解释了纳米尺度颗粒的形成,但这一研究领域的发展主要集中在利用纳米颗粒表面的配体控制参数,从而获得所需的形态和尺寸。与纳米结构表面结合的分子在形态控制和聚集过程中起作用,因为表面配体将功能特性转移到纳米结构上,从而显示出与该类材料的核心差异。本研究展示了纳米粒子表面功能化的最新进展,无论是在其合成过程中还是在修饰纳米粒子表面的后续步骤中,都可以使用配体。我们还讨论了基于路易斯酸碱特性的配体分类及其对纳米粒子胶体稳定性的影响,使我们能够分析溶剂与配体之间的相互作用,这种相互作用将配体的特性传递给纳米粒子,从而产生絮凝或分散的胶体溶液。
