下一代电子产品的飞速发展对热管理提出了更高的要求。初始石墨烯的导热性是铜的13倍。本文通过快速热处理化学气相沉积(RTP-CVD)法制备了具有大sp^(2)结构域的单层、双层和多层石墨烯(SLG、BLG、FLG),进一步通过低浓度H_(2)还原制备了高导热石墨烯。在1000℃下生长25 min制备出SLG,利用拉曼光谱和透射电子显微镜(TEM)研究了石墨烯的品质。为了验证RTP-CVD法生成的石墨烯的散热能力,将其作为2TB固态硬盘的散热器,通过红外热成像仪进行了研究。结果证明,RTP-CVD生长的石墨烯用于消费电子产品的热管理测试时性能表现优异。SLG显示温度(最高)比商用铜散热器低5℃,SLG的散热能力比商用铜散热器快200倍左右。综上,利用RTP-CVD法制备的轻质的柔性石墨烯可以成为下一代5G设备和消费电子产品热管理的更好选择。
