摘要
埃洛石Al2Si2O5(OH)4.nH2O是一种天然的纳米管材料,基于其中空结构、高长径比、低羟基密度等特性,通过物理、化学手段进行修饰可以获得性能优异的新型功能材料,已成为材料、化学、物理、电子等多学科交叉研究的前沿领域。在介绍埃洛石纳米管结构特性的基础上,系统总结了天然纳米管通过功能修饰制备新材料的国内外最新研究进展,包括生态环境材料、催化材料、仿生材料、有机/无机杂化材料、生物医药材料和储能材料。阐述了其制备技术、表征手段、结构形貌和功能特性等,展示了这些新型功能材料的广阔应用前景。
Halloysite is a natural nanotube with stoichiometry as AhSizOs （OH）4 ~ nHzO. Based on various characteristics such as nanoscale lumens, high length-to-diameter ratio, relatively low hydroxyl group density on the surface, etc. new functional materials can be obtained by physical or chemical modifications, which is a rapidly develo- ping research area lying at the nexus of materials, chemistry, physics, electronics. This review systematically summa- rizes the latest progress of a research all over the world that natural nanotube can be transferred to new materials by functional modification, based on the structural characteristics of the halloysite nanotube. The progress has been seen in environment, catalytic, organic-inorganic hybrid material, medicine, and energy storage. It states preparations, characterizing methods, morphology and functional characteristics, and also presents the bright future of these new functional materials.
