Abstract

Collecting urine samples from cats is a significant challenge for veterinarians due to their instinctive behavior to bury waste. The introduction of superhydrophobic cat soil, which prevents urine absorption, offers an innovative solution. This not only simplifies the diagnostic process for veterinarians but also significantly reduces stress for pets and their owners. In this study, we synthesized a hydrophobic coating using zinc oxide/silica composite nanoparticles (ZnO/SiO₂ CNPs) modified with perfluorodecyltrichlorosilane (FDTS) compounds for various surfaces such as soil, sand, stone, and glass. Tetraethoxysilane (TEOS) and zinc acetate dihydrate were used as precursors, while FDTS was employed for surface modification. The prepared ZnO/SiO₂ composite sol was sprayed onto different coatings, and the resulting hydrophobicity was confirmed by water contact angles, with an average angle of 110.3° for cat soil. Structural and morphological features of the synthesized ZnO/SiO₂ CNPs were analyzed using XRD, FTIR, EDX, and FESEM techniques. The chemical resistance of the coated stone was tested in acidic and neutral environments, showing better hydrophobicity in the neutral condition. The study highlights the potential of this composite to enhance agricultural practices in arid regions, facilitate pet urine collection in veterinary medicine, and offer various environmental benefits.

利用改性氧化锌/二氧化硅复合纳米粒子轻松制备疏水涂层

由于猫有掩埋排泄物的本能行为，因此收集猫的尿液样本对兽医来说是一项巨大的挑战。超疏水性猫尿土壤的引入提供了一种创新的解决方案，它可以防止猫咪吸收尿液。这不仅简化了兽医的诊断过程，还大大减轻了宠物及其主人的压力。在这项研究中，我们利用全氟癸基三氯硅烷（FDTS）化合物修饰的氧化锌/二氧化硅复合纳米粒子（ZnO/SiO2 CNPs）合成了一种疏水涂层，可用于土壤、沙子、石头和玻璃等各种表面。四乙氧基硅烷（TEOS）和二水醋酸锌被用作前驱体，而 FDTS 被用于表面改性。将制备好的 ZnO/SiO2 复合溶胶喷涂到不同的涂层上，通过水接触角确认了所产生的疏水性，其中猫科动物土壤的平均水接触角为 110.3°。利用 XRD、FTIR、EDX 和 FESEM 技术分析了合成的 ZnO/SiO2 CNP 的结构和形态特征。在酸性和中性环境中测试了涂覆石材的耐化学性，结果表明在中性条件下具有更好的疏水性。该研究强调了这种复合材料在改善干旱地区农业生产、促进兽医领域宠物尿液收集以及提供各种环境效益方面的潜力。图文摘要

期刊介绍： The journal Silicon is intended to serve all those involved in studying the role of silicon as an enabling element in materials science. There are no restrictions on disciplinary boundaries provided the focus is on silicon-based materials or adds significantly to the understanding of such materials. Accordingly, such contributions are welcome in the areas of inorganic and organic chemistry, physics, biology, engineering, nanoscience, environmental science, electronics and optoelectronics, and modeling and theory. Relevant silicon-based materials include, but are not limited to, semiconductors, polymers, composites, ceramics, glasses, coatings, resins, composites, small molecules, and thin films.
