摘要
蛭石是一种环境友好型天然硅酸盐矿物,具有独特的层状结构和稳定的物理化学性质.蛭石具有较高的孔隙率和较低的层间结合能,易于剥离形成二维(2D)纳米片应用于构建新型复合功能材料.本文聚焦蛭石纳米片的改性与高附加值应用,介绍了层状材料的种类与剥离方法、蛭石的结构与性质,阐述了蛭石在离子通道、生物医学、吸附、气体阻隔、催化、储能等方面的应用进展.最后针对蛭石研究存在的主要问题,展望了其未来发展趋势.
Abstract
Vermiculite is an environment-friendly natural silicate mineral,possessing a unique layered structure and stable physico-chemical properties.The high porosity and low interlayer binding energy endow its exfoliation into two-dimensional(2D)nanosheets,which can be further used to build new composite functional materials.To focus on the modification of vermiculite nanosheets and their high-value applications,this review describes the kinds and exfoliating methods of natural layered materials,expounds the structure and properties of 2D vermiculite nanosheets,and systematically elaborates the research progress of vermiculite nanosheets in ion channel,biomedicine,adsorption,gas barrier,catalysis,energy storage,and other aspects.Finally,in response to the existing problems in the study of vermiculite,the future development trends were discussed.
