摘要

Graphene is a two-dimensional material that possesses excellent thermal properties and thus has gained an enormous attention in the applications of heat transfer. In this work, we demonstrate the enhancement of boiling heat transfer performance on substrate coated with graphene oxide and/or copper composites. The graphene oxide and/or copper composites were introduced on the substrate by two commonly used coating techniques - dip-coating and a two-step electrochemical deposition method. The focus of this paper is to compare the morphologies, surface properties such as wickability and porosity rendered by these coating methods and compare the resultant heat transfer coefficients and critical heat fluxes. The surfaces were characterized by Scanning Electron Microscope (SEM), X-Ray Diffraction (XRD), and Fourier Transform Infrared (FTIR) techniques. Critical Heat Flux of 220 W/cm~2 at the wall superheat of 14.8°C was achieved for the highest 2.5% GO-Cu electrodeposited chip, while CHF of 128 W/cm~2 at the wall superheat of 13.2°C was achieved for the 5 minutes dip coated test surface.
