Abstract

Owing to the significant increase in air pollutants and the spread of infectious diseases, it seems that the use of face masks will become an essential item in human societies. Therefore, there is a need to conduct more research to develop novel types of respirators utilizing up-to-date science such as nanotechnology. In this study, we fabricated a nanocomposite fibrous filter containing modified graphene oxide (GO) and zinc oxide (ZnO) nanoparticles. This layer was used as an active filter for absorbing and removing air pollutants, such as suspended submicron particles (below 2.5 microns) and CO₂, NO₂, and SO₂ gases. The synthesized nanostructures and fibrous filters were characterized by different analysis (FTIR, XRD, TGA, and FESEM), and the performance of the filters was surveyed by tests such as pressure drop, CO₂, NO₂, SO₂ gas rejection, and particulate removal. The results showed that the stabilization of the modified GO and ZnO nanostructures on the fibrous filter improved the effectiveness of this filter as a mask for removing toxic particles and gases, and the filter containing nanoparticles had the best performance.

用电纺法制造改性纤维过滤器并研究其在改良面罩中的应用

由于空气污染物的大幅增加和传染病的传播，使用口罩似乎将成为人类社会的必备品。因此，有必要开展更多研究，利用最新科学（如纳米技术）开发新型呼吸器。在这项研究中，我们制作了一种含有改性氧化石墨烯（GO）和纳米氧化锌（ZnO）的纳米复合纤维过滤器。该层可用作活性过滤器，用于吸收和去除空气中的污染物，如亚微米悬浮颗粒（2.5 微米以下）以及 CO2、NO2 和 SO2 气体。通过不同的分析（傅立叶变换红外光谱、XRD、TGA 和 FESEM）对合成的纳米结构和纤维过滤器进行了表征，并通过压降、二氧化碳、二氧化氮、二氧化硫气体阻隔和颗粒物去除等测试对过滤器的性能进行了调查。结果表明，改性 GO 和 ZnO 纳米结构在纤维过滤器上的稳定化提高了该过滤器作为面罩去除有毒颗粒和气体的效果，其中含有纳米颗粒的过滤器性能最佳。

期刊介绍： Chinese Journal of Polymer Science (CJPS) is a monthly journal published in English and sponsored by the Chinese Chemical Society and the Institute of Chemistry, Chinese Academy of Sciences. CJPS is edited by a distinguished Editorial Board headed by Professor Qi-Feng Zhou and supported by an International Advisory Board in which many famous active polymer scientists all over the world are included. The journal was first published in 1983 under the title Polymer Communications and has the current name since 1985. CJPS is a peer-reviewed journal dedicated to the timely publication of original research ideas and results in the field of polymer science. The issues may carry regular papers, rapid communications and notes as well as feature articles. As a leading polymer journal in China published in English, CJPS reflects the new achievements obtained in various laboratories of China, CJPS also includes papers submitted by scientists of different countries and regions outside of China, reflecting the international nature of the journal.
