A series of biomimetic electronic nose nanomaterials of WO, WO@PDA, WO@PDA@CuO, WO@CuO and CuO were prepared by a facile method and their microstructures, surface chemical composition and sensing ability for acetone odor were investigated systematically by a variety of technologies. The WO@PDA@CuO and WO@CuO particles are in nano-sized shape, about 20 nm. The sensing ability to different concentrations acetone odor (50, 100 and 200 ppm) is addressed. The effect of different sensitivity definitions (R/R or |R - R|/R × 100%) on the comparison of experiment results is discussed. The WO@CuO sensing material shows the best sensing performance of all the sensors, being independent of concentration or sensitivity definitions. These results provide novel insights into the design and preparation of composite electronic nose sensing nanomaterials.
通过一种简便的方法制备了一系列仿生电子鼻纳米材料 WO、WO@PDA、WO@PDA@CuO、WO@CuO 和 CuO，并通过多种技术系统地研究了它们的微观结构、表面化学组成和对丙酮气味的传感能力。WO@PDA@CuO 和 WO@CuO 颗粒呈纳米级形状，约 20nm。研究了对不同浓度丙酮气味（50、100 和 200ppm）的传感能力。讨论了不同灵敏度定义（R/R 或 |R-R|/R×100%）对实验结果比较的影响。WO@CuO 传感材料在所有传感器中表现出最佳的传感性能，与浓度或灵敏度定义无关。这些结果为复合电子鼻传感纳米材料的设计和制备提供了新的思路。
