摘要

气溶胶颗粒对环境和人类健康起着重要作用。它们也越来越多地应用于医学(药物载体)、制备(纳米催化剂)和许多其他领域。对于这些应用,粒子必须具有直接由其结构和拓扑结构产生的独特性质。事实上,纳米结构粒子的功能是通过其应用来定义的,如色谱、传感器、微电子、催化等。这就是为什么人们对制造结构粒子越来越感兴趣的原因。结构粒子是具有明确的拓扑结构的粒子。这种粒子的例子是多孔粒子、中空粒子(内部有空白空间)或粒子结构中具有组分分离的多组分粒子。这种颗粒通常具有非常有趣的特征,例如多孔颗粒比体积相似的简单球形颗粒具有明显更大的表面积。本文全面综述了高有序结构粒子形成的数值模拟方法。将详细描述最重要的方法及其应用领域(具体示例),优点,局限性和有关其准确性的信息。

Numerical Modelling of Formation of Highly Ordered Structured Micro- and Nanoparticles – A Review
The aerosol particles play a significant role in the environment and human health. They are also increasingly used in medicine (drug carriers), preparation (nanocatalysts) and many other fields. For these applications, the particles have to possess unique properties which arise directly from their structure and topology. Indeed, the functionality of the nanostructure particle is defined through its application, like chromatography, sensors, microelectronics, catalysis, and others. That is the reason why people are more and more interested in manufacturing structured particles. The structured particles are the particles with well-defined topological structure. Examples of such particles are porous particles, hollow particles (with the empty space inside), or multi-component particles with the segregation of components in the particle structure. Such particles usually have very interesting features, e.g. porous particles have a significantly larger surface area than the simple spherical particles with similar volume. The present paper contains a comprehensive review of the numerical simulation methods of the formation of highly ordered structured particles. The most important methods will be described in detail and their fields of application (with specific examples), advantages, limitations and information about their accuracy will be given.
