Abstract
The coating of metal surface with carbon nanotubes(CNTs) has been studied for the heat transfer enhancement of the boiling and condensation of refrigerant. The multiwalled carbon nanotube/copper oxide(CuO) composite powder, which has been surface modified by dispersant and polyvinyl alcohol solution, was ultrasonically sprayed and sintered on a copper wafer. In this paper, experiments were performed to assess the characterization and comparison of the carbon nanotube before and after sinterning and the morphology changes of the CNT/CuO-coated surface by using different dispersants. The dispersants used are THF (Tetrahydrofuran), SDBS(Dodecylbenzenesulfonic acid sodium salt), SDS(Sodium dodecy sulfate). The samples were examined by scanning electron microscopy(SEM), thermogravimetric analysis(TGA), differential scanning calorimeter(DSC) and Raman spectroscopy.
