【摘要】 以三维石墨烯和噻吩为原料,利用化学氧化聚合法合成二元杂化材料三维石墨烯/聚噻吩（3D-rGO/PTh）,噻吩单体在载体石墨烯片的表面发生聚合反应。杂化材料表征使用扫描电镜、红外光谱仪和比表面测试仪。结果表明,杂化材料有大量空隙,具有较大的比表面积。室温下,石墨烯质量含量7%时,复合物对NO₂具有较好的气敏性能,NO₂浓度10×10^-6时,灵敏度达到34.1。复合材料气敏性能提高的原因在于大比表面积和协同效应。更多还原

【Abstract】 NO₂ gas sensor based on three dimensional graphene/polythiophene（3D-rGO/PTh）hybrid was presented.PTh 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.The NO₂ gas sensing performance of hybrid was studied and compared with that of the sensor based on bare PTh.3D-rGO/PTh showed better response to NO₂ gas than that of bare PTh.The sensitivity could reach 34.1for NO₂ of 10×10^-6.It shown that the synergetic behavior and large surface area allowed excellent sensitivity.更多还原
