Preparation of functionalized graphene/thermal conductive polyurethane films

Graphene/polymer composites have been widely used as thermal conductive materials in electronic equipment. However, the development of advanced graphene thermal conductive composites faces many problems, such as easy agglomeration, high interfacial thermal resistance and poor mechanical properties. In our work, new graphene-based polyurethane thermal conductive composites based on octadecylamine (ODA), graphene and thermoplastic polyurethane were prepared. The thermal conductivity(λ) of the composites reached 1.46W/(mK) with loading 20wt.%mRGO, which was increased by 326.02% compared with that of TPU. (paper)
