A preparation method of copper foam includes coating copper paste on a release film to form a coating sheet with a thickness of 50-200 μm on the release film, peeling off the release film to obtain a copper foam preform after drying the release film with the coating sheet, and performing a glue discharging process on the copper foam preform and sintering the copper foam preform to obtain the copper foam having a thickness of 30-120 μm and having a porosity of 50-80%. The thickness of the copper foam is reduced, which ensures a balance between the porosity and a structural strength of the copper foam, so the copper foam has a good water absorption performance, and a heat dissipation performance of the copper foam is effectively improved.
