摘要

以六水硝酸和尿素为前驱物，在100℃下水热法制备NiO，并通过扫描电镜和x射线衍射（XRD）观察其形貌、尺寸和结构。采用CGS-8气敏分析系统表征了NiO对乙醇蒸气的气敏性。结果表明，加入聚偏氟乙烯（PVDF）后，nio基气体传感器的灵敏度由1.82提高到3.25；研究了气敏性能增强的机理。

Enhanced NiO-based gas sensing performance to ethanol: the case of polyvinylidene fluoride

NiO were prepared by hydrothermal method using nitrate hexahydrate and urea as precursors at 100°C for 12 h. The morphology, size and structure was observed by scanning electron microscope and X-ray diffraction (XRD). The gas sensitivity of NiO to ethanol vapor was characterized by CGS-8 gas sensing analysis system. The results showed that the sensitivity of NiO-based gas sensor increased from 1.82 to 3.25 under the additive of polyvinylidene fluoride (PVDF). The mechanism of the enhanced gas sensing performance was investigated.

期刊介绍： The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
