摘要 以三维石墨烯和苯胺为原料,使用化学氧化聚合法制备二元复合材料三维石墨烯/聚苯胺纳米线(3D-rGO/PANI),石墨烯既是气敏材料的组成部分,又是聚苯胺的生长模板。复合材料的结构表征使用扫描电镜、红外光谱仪和比表面测试仪。结果表明:PANI是线状结构,复合材料有大量空隙,比表面积大。室温下,和纯PANI相比,3D-rGO/PANI对H2表现出较好的气敏性能,H2浓度为500×10-6时,灵敏度达到10.6。复合材料的大比表面积和协同效应有助于气敏性能提高。

Abstract: A hydrogen gas sensor based on three dimensional graphene/polyaniline (3D-rGO/PANI) hybrid were presented.PANI nanofibers were anchored on the surface of 3D-rGO sheets by using 3D-rGO as templates.The developed hybrid was characterized by SEM,FT-IR and BET analysis.H2 gas sensing performance of hybrid was studied and compared with that of sensor based on bare PANI nanofibers.It shown that the synergetic behavior and large surface area of hybrid allowed excellent sensitivity.3D-rGO/PANI sensor showed better response to H2 gas than that of bare PANI nanofiber.The sensitivity could reach 10.6 for H2 of 500×10-6.
Key words:  3D-rGO    PANI nanofiber    gas sensing property    room temperature
