Method for continuously preparing graphene heat-conducting films
The present disclosure relates to graphene. In particular, the present disclosure relates to a method for continuously preparing thermally conductive graphene films. A graphite oxide containing 40-60 wt % of moisture is directly stripped at a high temperature; and then, procedures such as dispersion, defoaming, coating, stripping, trimming, and reduction are performed to prepare thermally conductive graphene films with high thermal conductivity coefficient and strong electromagnetic shielding effectiveness. In the method, because of directly stripping the graphite oxide containing 40-60 wt % of moisture at a high temperature, the procedure of drying the graphite oxide is omitted, achieving low energy consumption and low manufacturing costs. Compared with preparing slurry by directly dispersing the graphite oxide, the concentration of the slurry after high temperature stripping is higher, and can reach 3-20 wt %.
