Abstract

In solutions, fullerenes, carbon nanoparticles with size of the order of one nanometer, exhibit a number of interesting properties and kinetic effects. A large part of these effects is connected with the ability of these macromolecules to form aggregates (or clusters), in which the nanoparticles are bound together by dispersion interactions. In this review, we present results of modeling of the kinetics of clusters formation and growth in fullerene C₆₀ solutions of different polarity. The basic approach is the numerical solution of a system of kinetic equations of nucleation theory, applied here for the description of aggregation of fullerenes and accompanying effects. The non-monotonous time dependence of fullerene concentration during dissolution was investigated. A molecular-colloidal solution transition in polar systems is described. In addition, a model description of the critical effect of cluster decomposition after water addition to certain fullerene solutions is presented.

富勒烯溶液中的动力学过程

摘要

在溶液中，富勒烯是大小为一纳米量级的碳纳米颗粒，具有许多有趣的特性和动力学效果。这些影响的很大一部分与这些大分子形成聚集体（或簇）的能力有关，其中纳米颗粒通过分散相互作用而结合在一起。在这篇综述中，我们介绍了富勒烯C ₆₀中团簇形成和生长动力学的建模结果。不同极性的溶液。基本方法是成核理论动力学方程组的数值解，此处用于描述富勒烯的聚集及其伴随效应。研究了富勒烯浓度在溶解过程中的非单调时间依赖性。描述了极性系统中的分子胶体溶液转变。此外，模型描述了在向某些富勒烯溶液中加水后团簇分解的关键作用。
