摘要
Hierarchically porous Cu with controlled pore characteristics and mechanical properties were fabricated from CuO powders and NaCl as template. NaCl particles were removed by dissolution from the pre-sintered CuO pellet using deionized water. CuO was decomposed to Cu during sintering at 900 degrees C in vacuum and resulted in porous Cu with bimodal pores. The porosity of porous Cu increased with increased NaCl content in the initial CuO pellet. The compression strength tests suggested that highly porous Cu were suitable for high impact energy absorption applications. Moreover, porosity, pore size and shape and mechanical properties of porous Cu could be tailored by tailoring the morphology and volume fraction of NaCl particles in the initial CuO pellet.
