摘　　要：为改善碳泡沫复合材料的性能,以低成本、短周期的一步碳化法制备了兼具柔性传感与超级电容器特性的三聚氰胺源多孔碳泡沫复合材料,研究了热处理温度对碳泡沫复合材料性能的影响。结果表明:碳泡沫复合材料为三维多孔网状结构,碳骨架在节点处部分呈凹形纤维状;经800℃热处理得到的碳泡沫复合材料比电容较大,为223.9 F/g,满足赝电容器电极材料的要求;经650℃以上热处理制备的碳泡沫复合材料灵敏度较好,将其作为压阻式传感器,可快速响应并精确分辨0.196~9.800kPa内的外部载荷。研究表明,制备的碳泡沫复合材料可以很好地应用于压应力传感器与超级电容器。In order to improve the properties of carbon foam composites,one step carbonization,featuring low cost and short cycle was employed to prepare melamine-derived porous carbon foam composites with the characteristics of flexible sensoring and super capacitor.The influence of heat treatment temperature on properties of carbon foam composites was investigated.Results show that carbon foam composites have a three-dimensional porous network structure,the carbon skeleton is partly concave fibrous at the node.The specific capacitance of carbon foam composites obtained by heat treatment at 800℃,is 223.9 F/g,which meets the requirement of electrode materials for pseudo capacitors.Carbon foams composites prepared by heat treatment above 650°C show good sensitivity,and thus could be used as a piezoresistive sensor,which respond to external loads within 0.196 kPa to 9.800 kPa quickly,and also resolve them accurately.Re⁃searches show that the prepared carbon foam composites can be well used in compressive stress sensors and super capacitors.
