海泡石表征技术研究:现状、挑战与展望OA

Sepiolite is an important raw material in China's strategic emerging industries.It has unique fibrous microstructure,high specific surface area,strong adsorption,low cost and abundant reserves.It shows broad applica-tion prospects in functional materials,environmental remediation,biomedicine and other fields.However,the perfor-mance of sepiolite is highly dependent on its chemical composition,crystal structure and surface properties.Therefore,accurate characterization of its physicochemical properties is the key to achieve efficient applications.This paper com-prehensively summarizes the characterization techniques for chemical composition,crystal structure,pore structure,surface morphology and surface properties of sepiolite,and compares and analyzes the advantages and disadvantages of various characterization techniques and applicable scenarios.At present,the key challenges faced by sepiolite charac-terization technology are multi-component complex system interference,the limitation of accurate analysis of nano-scale and multi-level structures,the limitation of in-situ monitoring of surface and interface dynamic behavior,the lack of stan-dardization and quantitative analysis,and the cross-domain challenges for different application scenarios.In the future,we should focus on multi-technology combination and algorithm optimization,in-situ dynamic platform deve-lopment,standard system expansion,artificial intelligence-assisted modeling,etc.,in order to achieve innovative breakthroughs in characterization technology.
