Abstract

Thin films produced by deposition of metal oxides on different surfaces show semi-conductor properties that are sensitive to the surrounding atmosphere components. With their optical, electrical, and structural properties, CdO metal oxides are used in a variety of fields ranging from optoelectronic materials to gas sensors. CdO thin films can be produced by different methods such as spray pyrolysis, SILAR, sol-gel spin coating and dip coating technique. The sol-gel dip coating technique, which is simple, accessible, adjustable, and repeatable based on desired parameters, is widely used in the production of CdO thin films. In this study, CdO metal oxide thin films were coated on polyamide, acrylic and cotton yarns by sol-gel dipping method in three different molarities of 0.1 M, 0.3 M and 0.5 M starting solutions. Structural properties of CdO thin film coated yarn samples were investigated using SEM and EDX analyzes were performed. The sensor tests of the yarn samples for LPG gas were carried out in the specially designed gas sensor measurement system and in the gas chamber. The 0.5 M CdO thin film coated cotton yarn samples showed better semiconductor properties and gas response than the other samples.
浸渍法在纱线上沉积CdO半导体及其气体传感器的应用
通过在不同表面沉积金属氧化物产生的薄膜显示出对周围大气成分敏感的半导体特性。CdO金属氧化物具有光学、电学和结构特性,广泛应用于从光电子材料到气体传感器的各个领域。CdO薄膜可以通过喷雾热解、SILAR、溶胶-凝胶旋涂和浸涂等不同方法制备。溶胶-凝胶浸涂技术是一种简单、易用、可调、可重复的CdO薄膜制备技术。在本研究中,采用溶胶-凝胶浸渍法,在0.1M、0.3M和0.5M的三种不同摩尔浓度的起始溶液中,将CdO金属氧化物薄膜涂覆在聚酰胺、丙烯酸和棉纱上。用扫描电镜研究了CdO薄膜涂层纱线样品的结构性能,并进行了EDX分析。在专门设计的气体传感器测量系统和气室中对纱线样品进行了LPG气体传感器测试。0.5M CdO薄膜涂层棉纱样品显示出比其他样品更好的半导体性能和气体响应。
