Study of synthesis, stability and thermo-physical properties of graphene nanoplatelet/platinum hybrid nanofluid

In the present study a new synthesis method has been introduced for the decoration of platinum (Pt) on the functionalized graphene nanoplatelet (GNP) and also highlighted the preparation method of nanofluids. GNP–Pt uniform nanocomposite was produced from a simple chemical reaction procedure, which...
