Volatile organic compounds (VOCs) are potentially dangerous to the environment and human health. The developed sensing template in this study was prepared by a one-step process on a glass substrate using the electrospinning technique. The sensing material made of the uniaxial aligned CdSe-CdS/Ag/PMMA composite scaffold consists of CdSe-CdS core-shell quantum rods, silver nanoparticles (Ag NPs), and poly(methyl methacrylate) (PMMA) nanofibers. Increasing the specific surface area is beneficial for VOCs harvesting; therefore, the uniaxial aligned CdSe-CdS/Ag/PMMA composite scaffold was slightly treated with UV-ozone etching, and thus efficiently enhancing the extinction changes of VOCs. Also, a high VOC detection capability was demonstrated by the polarization response and Ag surface plasmon resonance of the nanocomposite. A series of typical VOCs and alcoholic VOCs were used for the VOCs sensor practical tests. This VOC sensor achieved a spectacular detection limit of 100 ppm for butanol and 500 ppm for chlorobenzene. The uniaxial aligned CdSe-CdS/Ag/PMMA composite scaffold is a newly designed nanocomposite and can reach the market demands comparing to other commercial high sensitive VOC sensors.

挥发性有机化合物（VOC）对环境和人类健康具有潜在危险。本研究中开发的传感模板是使用静电纺丝技术通过一步法在玻璃基板上制备的。由单轴排列的CdSe-CdS / Ag / PMMA复合支架制成的传感材料由CdSe-CdS核-壳量子棒，银纳米颗粒（Ag NPs）和聚甲基丙烯酸甲酯（PMMA）纳米纤维组成。增加比表面积有利于VOC的收获；因此，单轴取向的CdSe-CdS / Ag / PMMA复合支架经过紫外臭氧刻蚀处理，从而有效增强了VOCs的消光变化。此外，纳米复合材料的极化响应和Ag表面等离振子共振显示出较高的VOC检测能力。一系列典型的VOC和含酒精的VOC用于VOC传感器的实际测试。这款VOC传感器对丁醇的检测极限达到了惊人的100 ppm，对氯苯的检测极限为500 ppm。单轴排列的CdSe-CdS / Ag / PMMA复合支架是一种新型设计的纳米复合材料，与其他商用高灵敏度VOC传感器相比，可以满足市场需求。
