一种基于石墨烯散的散热膜的制备方法，包括以下步骤：
1）采用压延法制得两侧带有离型纸的双面胶，双面胶主要由酚醛树脂80-95%、胶黏剂2-5%和碳纳米管1-3%构成，胶黏剂和碳纳米管超声分散于酚醛树脂中；
2）以氧化石墨烯为基体,醋酸锌为锌源,采用溶胶法制备导热散热膜，并将导热散热膜采用PET膜进行背膜加固；
3）将步骤1）中制得的双面胶撕除一侧的离型纸对导热散热膜进行背胶加固，既得基于石墨烯散的散热膜。
本发明的有益效果是：本发明制作简单，基于石墨烯制成的导热散热膜具有柔韧性，可以自动化连续生产，可以卷曲储存，使用方便，导热散热效果好，使用方便，可以广泛用于笔记本电脑、手机、电视、摄像机、LED灯以及汽车散热片等设备的导热散热。
