Abstract
本发明提供一种高导热石墨烯气凝胶减震垫片及其制备方法，通过限高热压定型法使取向氧化石墨烯气凝胶表层塌缩并使其内部产生不完全压缩，热处理后同时得到具有高垂直取向的石墨烯主体层和高平行取向的石墨烯皮层，热压过程中皮层石墨烯塌缩产生的层间Π‑Π相互作用和主体层石墨烯不完全压缩产生的片间嵌合结构可有效提高导热垫片的柔性及界面的抗撕裂强度。特定热处理温度下石墨烯片层表面官能团和面外碳原子形成的交联结构赋予导热垫片高回弹性和高回弹速率，低压缩模量的气凝胶结构可有效卸载电子器件振动过程中产生的应力。所得垫片能满足电子基站、通讯雷达、新能源汽车和航空航天等电子设备在减震防震零部件处的热管理需求。
