## Description

- description: With the rapid development of the electronics industry, the demand
    for superior heat dissipation materials is increasing. Although many studies have
    been conducted on graphene films with high thermal conductivity, most of them
    are processed at high temperatures (∼3000 °C) using graphene oxide, which is environmentally
    harmful and consumes large amounts of energy. This paper reports a simple, low-cost,
    low-energy, high-efficiency method for the preparation of graphite films using
    only environmentally friendly materials. Composite films with a thermal conductivity
    of 298.5 Wm-1K-1 were successfully produced by simply dispersing and exfoliating
    natural graphite and carboxymethylcellulose in a roll mill and depositing by blade
    coating. Conventional films fabricated using graphene nanoplates (GNP) exhibited
    a thermal conductivity of 94.6 Wm-1K-1, which is significantly lower than the
    graphite film produced by roll-milling. Experimental and theoretical investigations
    reveal the reason for this is that the mixed structure of large graphite and small
    graphite/GNP reduces the interfacial thermal resistance while forming a denser
    network of heat conduction paths.
