摘　　要：简述了我国近年来可膨胀石墨的制备方法、开发利用现状,概述了可膨胀石墨在环保、密封、电池、防火阻燃、电子散热、生物医学、军事等领域的应用;重点总结了制备可膨胀石墨的方法和常用的氧化剂和插层剂,介绍了可膨胀石墨制备中氧化插层剂的筛选应用现状与不足;展望了膨胀石墨未来的研发趋势,指出未来插层与膨胀过程的有机结合将大有可为。The preparation methods, development and utilization of the expandable graphite are briefly introduced. The applications of expandable graphite are described, including environmental protection, sealing, batteries, fire retardant, electronics cooling, bio-medical, military and other applications. The preparation of expandable graphite, the commonly used oxidants and intercalation agents are highlighted. Current situation and drawbacks of the selections and applications of oxide intercalation agents are described. The future development trends of expansible graphite are put forward. The combination of intercalation and expansion process will be the new direction in the future.
