摘　　要：为探讨氧化石墨烯复合材料的气敏性,以氧化石墨烯(GOs)、乙酸锌(C4H6O4Zn)、尿素(CO(NH_2)_2)为主要原料,采用水热法制备GOs/ZnO复合材料并研究其对乙醇气体的敏感性。以乙酸锌、尿素及GOs为原料,在无水乙醇体系中合成ZnO含量不同的GOs/ZnO复合材料,并对其进行XRD、SEM及FTIR表征及气敏性能的测试,研究讨论了温度、ZnO含量、乙醇浓度等各因素对复合材料敏感性的影响。结果表明,在工作温度为60℃时,氧化石墨烯/ZnO(ZnO含量为15%)具有乙醇最佳的气敏响应,显示了良好的气体敏感性,且GOs/ZnC复合材料有良好的长期使用性,可以用于检测乙醇的气体浓度。In this paper, graphite oxide（GOs）, zinc acetate（C4H6O4Zn）, urea（CO（NH2）2） as the raw material prepared GOs/ZnO composite materials by Hydrothermal, and study their sensitivity to ethanol gas. Zinc acetate, urea, and graphene oxide （GOs） as raw materials synthetize GOs/ZnO composite sensitive material with different content ZnO in ethanol of systems by Hydrothermal method, using XRD, SEM and FTIR to characterize and then testing its gas sensing performance. Studiedand and discussed the effects of temperature, ZnO content, ethanol concentration and other factors on the susceptibility of the composite material. The results showed that the GOs/ZnO （ZnO content of 15%） have the best ethanol gas sensing response at an operating temperature of 60℃, show a good gas sensitivity and long-term stability, and can be used for detecting gas concentration of ethanol.
