Method for preparing a nanofilm without an oxide substrate (FRGO) Graphene Reference

Abstract

Fabrication of a nanofilm as a heat sink for cooling electronic devices, electric motors, and patients using electrochemically reduced graphene oxide without a substrate, following this procedure: - Preparation of graphene oxide using the modified Hummers method. - Loading a stainless steel substrate with suspended graphene oxide and drying it. Electrochemical reduction of graphene oxide using a potentiostat in a three-electrode cell. - Washing and drying the prepared film. - Characterization of the film's structure using visible, ultraviolet, and infrared spectroscopy. The film's shape was characterized using atomic force microscopy and scanning electron microscopy. The film's ability to dissipate heat energy from the source to the surrounding environment was tested by temperature scanning.
