چکیده
High-efficient heat dissipation materials are urgently required in advanced electronic packaging technology because effectively releasing the internal flow density of devices is a key factor during their operation. In this work, novel vertical graphene nanosheets/carbon fibers (VGNs/CF) composite film, with vertically oriented structure and excellent properties, fabricated on stainless steel substrate by facile thermochemical growth method. The preparation film green, safe, highly efficient. CF used as thermally conductive filler to provide thermal conductivity channels for VGNs, both them construct continuous network. through-plane VGNs/CF could reach 17.7 W/(m·K), addition significantly improved performance compared pure VGNs (13.9 W/(m·K)). Conclusively, simple method outstanding capacity expected meet application requirements electronics industry.
