1、Four short words sum up what has lifted most successful individuals above the crowd: a little bit more.-author-date氧化石墨烯聚苯胺纳米复合材料的制备、表征及其潜在应用氧化石墨烯聚苯胺纳米复合材料的制备、表征及其潜在应用氧化石墨烯/聚苯胺纳米复合材料的制备、表征及其潜在应用摘要氧化石墨烯、导电聚苯胺是重要的多功能材料，在高能量的锂电池、超级电容器、催化、太阳能电池、化学传感、生物传感等领域有着较高的研究价值和潜在应用。本文采用化学氧化法制得了氧化石墨烯，之后利用原位聚合途径合成了氧

2、化石墨烯/导电聚苯胺纳米复合材料。采用透射电镜（TEM）,原子力显微镜(AFM)，红外光谱(FTIR)，UV-Vis，X-射线衍射（XRD）等进行了相应表征。为考察氧化石墨烯、氧化石墨烯/导电聚苯胺纳米复合材料的表面、界面特性，便于开发性能优异的纳电子器件，用所合成的纳/微米结构材料及其复合材料构筑了 QCM 结构化学传感器原型器件，对器件的吸附响应特性进行了对比考察。探讨了存在的不足，并提出了一些改进的建议。Praparation, Characterizations, and Its Potential Applications of PANi / Graphene Oxide Nanoc

3、ompositeAbstractGraphene oxide (GO), nano/micro-structured polyaniline (PANi) are some typical important functional materials, which have many applications in lithium ion battery with high energy, supercapacitor, catalysts, solar cells, nanodevices, chemical sensors, biosensors and biomedical fields

4、. In this paper, GO was obtained by using chemical oxidation method at room temperature, and nano/micro-structured GO/PANi composite was prepared with in-situ polymerization of aniline in the presence of GO suspension. A series of characterizations were examined by TEM (transmission electron microsc

To examine the surface and interface properties of GO, GO/PANi nanocomposite, chemical prototype sensors were constructed based on GO, GO/PANi nanocomposite and QCM device. The comparative response behaviors of the sensor to some typical volatile compounds operating at room temperature were investigated. The adsorption features to some typical volatile compounds were discussed. Some key issues and modification ideas were suggested for further investigation.-
