摘　　要：通过超声复合制备了氧化石墨烯GO含量不同(质量分数分别为2.5%,5%,10%)的氧化石墨烯/氧化钨(GO/WO_(3))复合材料,通过X射线衍射仪、场发射扫描电子显微镜和傅里叶变换红外光谱仪、气敏元件测试仪对复合材料的结构、形貌和气敏性能进行了表征和测试。结果表明:制备的GO/WO_(3)复合材料对三乙胺具有良好的选择性和稳定性;最佳工作温度为190℃时,对100ppm三乙胺气体的灵敏度达到了12.1;响应时间和恢复时间分别为21s和29s。GO/WO_(3)nanocomposites with different doping ratios(mass fractions of 2.5%,5%,10%)were prepared by ultrasound compounding method.The structure,morphology and gas sensitivity of the composite were characterized and tested using X-ray diffraction(XRD),scanning electron microscopy(SEM),and infrared spectroscopy(FT-IR).The results showed that the prepared gas sensing element exhibited excellent selectivity and stability for triethylamine.At an optimal operating temperature of 190℃,the sensitivity to 100 ppm triethylamine gas reached 12.1.In addition,the response time and recovery time were 21 s and 29 s,respectively.
