摘要
蛭石是中国优势非金属矿产之一,具有二维(2D)层状结构和独特的高膨胀性能等优点,可应用于构建新型功能材料,但其存在结构稳定性差和纳米尺度控制难等问题。该文阐述了天然层状蛭石的结构与性质,回顾了近年来国内外关于蛭石复合功能材料的相关报道,重点分析了蛭石的剥离与改性及其在吸附、催化剂载体、有机-无机复合材料、储能、药物载体等方面的研究进展。最后针对蛭石研究存在的主要问题,提出今后研究的重点在蛭石剥离,多级结构复合功能材料和有机-无机复合功能材料的构建,以及相关机理的探索。
Vermiculite is one of dominant non-metallic mineral in China. Vermiculite can be used to construct new functional materials due to its two-dimensional(2 D) layered material structure and high expansion performance. However, it has some problems such as poor structural stability and nano-scale being difficult to control. In this paper, we introduce the structure and properties of natural vermiculite and review the recent progress on vermiculite-base functional materials at home and abroad, Firstly, we focus on the exfoliation and modification of vermiculite. Subsequently, we discuss introduces the application of vermiculite in some fields, such as adsorption, catalyst support, organic and inorganic composites, energy storage and drug carrier. Finally, the research trends of vermiculite are brought forward. Exfoliation of vermiculite, construction of multi-structure composite functional materials and organic and inorganic composite functional materials, as well as the exploration of related mechanisms may be the focus of future research.
