Abstract: A method of forming copper oxide nanopowder includes dissolving copper metal bulk in an acidic solution to form a copper-containing solution, wherein the acidic solution is sulfuric acid or nitric acid. The method includes adding an alkaline solution into the copper-containing solution to precipitate a solid. The method includes filtering, collecting, and drying the solid. The method includes calcinating the solid to obtain copper oxide nanopowder. When the acidic solution is sulfuric acid, the copper oxide nanopowder is a combination of long-bar shaped and sheet-shaped. When the acidic solution is nitric acid, the copper oxide nanopowder is short-bar shaped. The copper oxide nanopowder and an aqueous resin can be mixed to form an electrically insulating and thermally conductive film.
