埃洛石的命名、结构、形貌和卷曲机制

Nomenclature, Structure, Morphology and Curling Mechanism of Halloysite

埃洛石作为一种典型的高岭石族矿物,大部分情况下呈现出管状形貌,近年来已被广泛用作缓释容器、催化剂载体、有机聚合物填充材料、储氢材料和纳米材料模板等,具有重要的应用价值。对埃洛石微观化学信息的研究,不仅有助于理解埃洛石地质成因、掌握埃洛石结构细节,还有助于提高埃洛石使用性能、拓宽其应用范围。本文针对埃洛石的结构、形貌和发生卷曲的机理等进行了详细介绍;此外,鉴于长期以来埃洛石名称的混乱状态,本文还对其命名历史进行必要综述。在此基础上,给出埃洛石的中文建议名称,提出目前结构研究中存在的一些问题,并对未来的研究方向进行了展望。

As a typical mineral of kaolinite group, halloysite shows tubular morphology in most cases. In recent years it has been widely used as sustained-release container, catalyst support, and filler material for organic polymer, hydrogen storage materials and nanomaterials template, and has important application value. Research on the microscopic chemical information not only helps us to understand the geological origin of halloysite and master the halloysite structure, but also improves its functional performance and broadens its application. In this review, the structure, morphology and curling mechanism were discussed in detail; in addition, in view of the long-standing confusion of halloysite name, the history of nomenclature of halloysite was necessarily summered. Finally, the halloysite Chinese name was recommended, the existing issues in structure research were analyzed and the outlooks for the further research in this field were proposed.
