Abstract

The growing demand for superior gas sensors has led researchers to increasingly focus on materials characterization, given its critical role in enhancing gas sensing capabilities. In this study, different withdrawal speeds were investigated on the properties of CuO films deposited using the sol-gel dip-coating technique. The findings revealed that the optimal conditions for the CuO film were achieved at a withdrawal speed of 70 mm/min. The XRD results indicated that all CuO films exhibits pure CuO phase resembling higher crystallinity and larger crystallite sizes. Surface morphology from FESEM analysis revealed more uniform surfaces and well-developed flower-like structures. For AFM results, topology images showed a smoother surface with low roughness. Surface profiler measurements observed that the film thickness have direct relationship toward withdrawal speeds, showing an optimal thickness and thinner films are at lower withdrawal speed. By utilizing the four-point probe, electrical resistivity measurements revealed a higher quality of structural and surface properties of films consequently led to a decrease in electrical resistivity. The results indicate that CuO films deposited at 70 mm/min have favorable features for gas sensor applications, highlighting the importance of withdrawal speed in optimizing film properties towards sensor performance.

提取速度对溶胶-凝胶浸镀CuO薄膜性能的影响

由于对优质气体传感器的需求不断增长，研究人员越来越关注材料的特性，因为它在增强气体传感能力方面起着关键作用。在本研究中，研究了不同提取速度对溶胶-凝胶浸涂技术沉积的CuO薄膜性能的影响。结果表明，在提取速度为70 mm/min时，制备CuO膜的最佳条件。XRD结果表明，所有CuO膜均表现为纯CuO相，具有较高的结晶度和较大的晶粒尺寸。FESEM分析的表面形貌显示出更均匀的表面和发育良好的花状结构。对于AFM结果，拓扑图像显示较光滑的表面，粗糙度较低。表面剖面仪测量发现，薄膜厚度与提取速度有直接关系，呈现出最佳厚度，而较薄的薄膜在较低的提取速度下。通过使用四点探头，电阻率测量揭示了更高质量的薄膜结构和表面特性，从而导致电阻率降低。结果表明，以70 mm/min的速度沉积的CuO薄膜具有良好的气体传感器应用特性，突出了提取速度在优化薄膜性能对传感器性能的重要性。图形抽象

期刊介绍： The primary objective of the Journal of Sol-Gel Science and Technology (JSST), the official journal of the International Sol-Gel Society, is to provide an international forum for the dissemination of scientific, technological, and general knowledge about materials processed by chemical nanotechnologies known as the "sol-gel" process. The materials of interest include gels, gel-derived glasses, ceramics in form of nano- and micro-powders, bulk, fibres, thin films and coatings as well as more recent materials such as hybrid organic-inorganic materials and composites. Such materials exhibit a wide range of optical, electronic, magnetic, chemical, environmental, and biomedical properties and functionalities. Methods for producing sol-gel-derived materials and the industrial uses of these materials are also of great interest.
