Hematite microparticles are becoming increasingly important components in the soft matter field. The remarkable combination of magnetic and photocatalytic properties that characterize them, coupled with the variety of uniform and monodisperse shapes that they can be synthesized in, makes them a one of a kind colloidal model system. Thanks to these properties, hematite microparticles have been recently applied in several important soft matter applications, spanning from novel colloidal building blocks for self-assembly to necessary tools to investigate and understand fundamental problems. In this review article we provide a detailed overview of the traditional methods available for the preparation of hematite microparticles of different shapes, devoting special attention on some of the most common hiccups that could hider a successful synthesis. We furthermore review the particles' most important physico-chemical properties and their most relevant applications in the soft matter field.
赤铁矿微粒正日益成为软物质领域中重要的组成部分。它们具有显著的磁性和光催化特性,再加上能够合成出的各种均匀且单分散的形状,使其成为独一无二的胶体模型系统。得益于这些特性,赤铁矿微粒最近已应用于多个重要的软物质应用中,从用于自组装的新型胶体构建块到研究和理解基本问题的必要工具。在这篇综述文章中,我们详细概述了用于制备不同形状赤铁矿微粒的传统方法,并特别关注了可能阻碍成功合成的一些最常见问题。此外,我们还综述了这些微粒最重要的物理化学性质及其在软物质领域中最相关的应用。
