开发了一种制造含有聚合物的闭孔材料的新方法。通过化学镀在聚苯乙烯粉末颗粒上涂覆镍磷合金层，并在高温下烧结。然后制造含有聚合物的金属闭孔材料。扫描电子显微镜观察和能量色散X射线光谱分析表明，热处理后聚合物仍保留在电池中。该材料的压缩测试显示出低杨氏模量和高能量吸收。超声波测量表明，这种细胞材料的衰减系数非常大，并且随着温度的升高而变化。
A new method for fabricating closed cellular materials containing polymers has been developed. Polystyrene powder particles coated with a nickel–phosphorus alloy layer by electroless plating, were sintered at high temperature. A metallic closed cellular material containing polymer was then fabricated. Scanning electron microscope observations and energy dispersive X-ray spectroscopy analysis indicated that polymer remains in the cells after heat treatment. The compressive tests of this material show a low Young's modulus and high-energy absorption. Ultrasonic measurements showed that the attenuation coefficient of this cellular material is very large and changes with increasing temperature.
