In the present work, biodegradable and flexible chitosan/polyvinylpyrrolidone (CHP) polymeric substrate was fabricated by solvent casting method. This is a novel demonstration of the combination of natural polymer (chitosan) and synthetic polymer (PVP) for next-generation semiconductor device applications. The ZnO thin films were successfully synthesized on these polymeric substrates by facile drop-casting method for gas sensing applications. The hydrogen gas sensing properties of ZnO deposited on the polymeric substrate and SiO2 substrate show similar performance. The structural, morphological, optical, thermal, and tensile strength of the CHP substrate were studied using X-ray diffraction (XRD), Scanning electron microscopy (SEM), UV-visible spectroscopy, Derivative thermogravimetric analysis (DTG), and Universal testing machine (UTM), respectively. Our study suggests that the biodegradable CH/PVP flexible polymeric substrate provides a new way for the implementation of an eco-friendly green substrate in numerous electronic device applications.

在柔性壳聚糖/ PVP混合聚合物基材上开发具有成本效益的基于金属氧化物半导体的气体传感器。

在本工作中，通过溶剂浇铸法制备了可生物降解的柔性壳聚糖/聚乙烯吡咯烷酮（CHP）聚合物基质。这是天然聚合物（壳聚糖）和合成聚合物（PVP）结合用于下一代半导体器件应用的新颖演示。ZnO薄膜是通过用于气体传感应用的简便滴铸法成功地在这些聚合物基板上合成的。沉积在聚合物基板和SiO2基板上的ZnO的氢气感测性能相似。使用X射线衍射（XRD），扫描电子显微镜（SEM），紫外可见光谱，导数热重分析（DTG）和通用测试机研究了CHP基板的结构，形态，光学，热和拉伸强度（UTM），分别。我们的研究表明，可生物降解的CH / PVP柔性聚合物基材为在众多电子设备应用中实施绿色环保的绿色基材提供了新途径。
