Description

一种石墨烯导电泡沫
技术领域
本实用新型属于材料技术领域，具体涉及一种石墨烯导电泡沫。
背景技术
导电泡沫是一种内部均匀分布着大量连通或不连通的气泡的导电固体材料，用于抗静电、电磁屏蔽、气敏或压敏传感器、污水净化等领域。导电泡沫常用的制备方法是聚合物中填充导电物质碳黑后经发泡工艺制备。
石墨烯是平面两维单原子层碳材料，是目前发现最坚硬的纳米材料，室温下石墨烯的电子迁移率达到106cm2V-1s-1，电阻率约10-6Ωcm，也是电阻率最小的材料。石墨烯的这些性能保证了由石墨烯制备的泡沫比普通泡沫材料具有更低的密度和更高的导电性能。
发明内容
本实用新型的目的是提供一种石墨烯导电泡沫。
本实用新型包括泡沫本体，泡沫本体内分布有气孔，泡沫本体表面及气孔表面涂覆有导电层。
所述的导电层为厚度是1～2                                               
Figure 2012200753750100002DEST_PATH_IMAGE002
的氧化石墨烯；
所述的泡沫为聚氨酯泡沫、聚苯乙烯泡沫、聚乙烯泡沫、聚氯乙烯泡沫或聚丙烯泡沫。
本实用新型具有密度低、电导率高、比表面积大、成本低的优点。泡沫表面的导电层石墨烯经水反复洗涤不脱落，用作环保设备污染物过滤的滤芯材料使用后经过清洗可以重复循环使用。传统气敏传感器制作工艺复杂、难度要求高、对周围环境要求苛刻与现有的传感器相比，而用石墨烯泡沫材料制备的新型气敏传感器可以克服上述缺点在气体探测以及环境探测中发挥重要作用。该石墨烯导电泡沫机械强度和弹性好，在挤压、弯曲等外力下电阻就会产生明显变化，可以用于制备新型振动传感器等等。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
如图1所示，一种石墨烯导电泡沫包括泡沫本体1，泡沫可以是聚氨酯泡沫、聚苯乙烯泡沫、聚乙烯泡沫、聚氯乙烯泡沫或聚丙烯泡沫。泡沫本体1内分布有大量连通或不连通的气孔2。泡沫本体1的表面及气孔2表面涂覆有1～2
