Abstract

In this study, graphene oxide (GO)-based nanocomposites containing zinc oxide (ZnO) and tin oxide (SnO₂) nanoparticles were fabricated and their structure, morphology, and self-cleaning properties were thoroughly examined. To the best of our knowledge, no effort has been made to prepare GO-ZnO and GO-SnO₂ nanocomposites and investigate their self-cleaning properties. In this regard, nanocomposites were initially synthesized by means of modified Hummer’s method, followed by combining GO with ZnO and SnO₂ nanoparticles. In order to anchor prepared thin films onto glass substrates, spray pyrolysis technique was employed.

As evidenced by X-ray diffraction (XRD) spectroscopy, SnO₂ and ZnO nanostructures respectively have tetragonal rutile and wurtzite phases. Morphological investigations conducted by means of field emission scanning electron microscopy (FE-SEM) and atomic force microscopy (AFM) respectively revealed uniform distribution of nanoparticles and considerable variations in surface roughness, which corroborate the comprehensiveness of our study. The hydrophobicity and self-cleaning properties of our fabricated nanocomposites were scrutinized using contact angle test.

The findings obtained from contact angle measurements demonstrated that the GO-SnO₂ nanocomposites outperform other composites in terms of hydrophobicity. The great characteristics of our GO-based nanocomposites showed their potential for sophisticated coating applications, mainly for cleaning the surfaces.

氧化石墨烯基纳米复合薄膜的结构、形态和自清洁特性的研究

在本研究中，制备了含有氧化锌（ZnO）和氧化锡（SnO2）纳米颗粒的氧化石墨烯（GO）基纳米复合材料，并对其结构、形态和自清洁性能进行了全面研究。据我们所知，目前还没有人研究GO-ZnO和GO-SnO2纳米复合材料的制备及其自清洁性能。因此，首先采用改进的Hummer方法合成纳米复合材料，然后将氧化石墨烯与ZnO和SnO2纳米颗粒结合。为了将制备好的薄膜固定在玻璃基板上，采用了喷雾热解技术。x射线衍射（XRD）证实，SnO2和ZnO纳米结构分别具有四方金红石和纤锌矿相。利用场发射扫描电镜（FE-SEM）和原子力显微镜（AFM）分别进行的形态学研究显示，纳米颗粒分布均匀，表面粗糙度变化较大，证实了我们研究的全面性。通过接触角测试，考察了纳米复合材料的疏水性和自清洁性能。接触角测量结果表明，氧化石墨烯- sno2纳米复合材料在疏水性方面优于其他复合材料。氧化石墨烯基纳米复合材料的优异特性显示了它们在复杂涂层应用方面的潜力，主要用于表面清洁。

期刊介绍： Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics. Results in Physics welcomes three types of papers: 1. Full research papers 2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as: - Data and/or a plot plus a description - Description of a new method or instrumentation - Negative results - Concept or design study 3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
