Abstract: Bentonite is a natural non-metallic mineral resource. Transforming it into valuable products through advanced technological means and applying them in various fields of social production such as industry, agriculture and environmental governance is an important way to achieve resource recycling and reduce negative environmental impacts. This paper reviews the current preparation methods, characterization techniques and application status of modified bentonite materials at home and abroad, summarizes the methods and principles for improving the performance of bentonite and the characterization and testing methods, analyzes the application potential and shortcomings of modified bentonite in soil improvement, remediation agents, fertilizer additives, pesticide adsorbents and fields such as electronics, automobiles and aerospace, and looks forward to the future development direction of modified bentonite materials, providing useful references and inspirations for the research and development of high-performance modified bentonite materials.

Key words: bentonite, composite material, intelligent material, sensing technology, environmental governance, modification, characterization
