Abstract

The uses of inorganic metal oxide as ultraviolet (UV) absorbers have potential to increase the production of UV protection and can also overcome the disadvantages of organic molecules. In this article, we report an effective technique to fabricating polyvinyl chloride (PVC) films with well UV shielding efficiency. Surface modification of zinc oxide (ZnO) nanoparticles (NPs) with different silane coupling-agents were achieved, and through solution casting technique dispersed within the PVC matrix. Infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and UV spectrophotometer were applied to study the structures, dispersions, and optical properties. The results showed that the functionalized ZnO NPs could be well dispersed in PVC and endow the polymer composite films with significantly improved anti-UV capability. The facile processing and obtained properties of PVC composites have shown potential for low cost and environmentally sustainable applications in the UV protection field.

制备硅烷偶联剂修饰的氧化锌纳米粒子，用于制造抗紫外线聚氯乙烯薄膜。

使用无机金属氧化物作为紫外线（UV）吸收剂具有提高紫外线防护性能的潜力，同时还能克服有机分子的缺点。在本文中，我们报告了一种制造具有良好紫外线屏蔽效果的聚氯乙烯（PVC）薄膜的有效技术。采用不同的硅烷偶联剂对氧化锌（ZnO）纳米粒子（NPs）进行表面改性，并通过溶液浇铸技术将其分散在聚氯乙烯基体中。应用红外光谱（FT-IR）、扫描电子显微镜（SEM）、热重分析（TGA）和紫外分光光度计研究了纳米粒子的结构、分散性和光学性能。结果表明，官能化 ZnO NPs 可以很好地分散在 PVC 中，并使聚合物复合薄膜的抗紫外线能力显著提高。聚氯乙烯复合材料加工简便，性能优异，有望在防紫外线领域实现低成本和环境可持续应用。

期刊介绍： Environmental Sociology is dedicated to applying and advancing the sociological imagination in relation to a wide variety of environmental challenges, controversies and issues, at every level from the global to local, from ‘world culture’ to diverse local perspectives. As an international, peer-reviewed scholarly journal, Environmental Sociology aims to stretch the conceptual and theoretical boundaries of both environmental and mainstream sociology, to highlight the relevance of sociological research for environmental policy and management, to disseminate the results of sociological research, and to engage in productive dialogue and debate with other disciplines in the social, natural and ecological sciences. Contributions may utilize a variety of theoretical orientations including, but not restricted to: critical theory, cultural sociology, ecofeminism, ecological modernization, environmental justice, organizational sociology, political ecology, political economy, post-colonial studies, risk theory, social psychology, science and technology studies, globalization, world-systems analysis, and so on. Cross- and transdisciplinary contributions are welcome where they demonstrate a novel attempt to understand social-ecological relationships in a manner that engages with the core concerns of sociology in social relationships, institutions, practices and processes. All methodological approaches in the environmental social sciences – qualitative, quantitative, integrative, spatial, policy analysis, etc. – are welcomed. Environmental Sociology welcomes high-quality submissions from scholars around the world.
