随着冠状病毒(CoV)大流行的爆发,口罩正成为最有用的个人防护装备之一。整个世界都在经历一次性口罩和熔喷无纺布的短缺,熔喷无纺布是口罩过滤器的原材料。废弃口罩的可回收性也成为环境的一大挑战。在这里,我们介绍了一种基于静电纺丝和三维打印的简便方法,以制作可更换和可生物降解的口罩过滤器。我们将聚乳酸(PLA)聚合物支柱印刷在PLA纤维网上,以制造具有分层结构和透明外观的纳米多孔过滤器。透明的外观克服了口罩的威胁性外观,这可能是减少当前CoV疾病-19大流行造成的社会创伤的可行方法。在这项研究中,我们研究了喷嘴温度对纳米多孔过滤器的光学,机械,形态和过滤性能的影响。
Face masks are becoming one of the most useful personal protective equipment with the outbreak of the coronavirus (CoV) pandemic. The entire world is experiencing shortage of disposable masks and melt-blown non-woven fabrics, which is the raw material of the mask filter. Recyclability of the discarded mask is also becoming a big challenge for the environment. Here, we introduce a facile method based on electrospinning and three-dimensional printing to make changeable and biodegradable mask filters. We printed polylactic acid (PLA) polymer struts on a PLA nanofiber web to fabricate a nanoporous filter with a hierarchical structure and transparent look. The transparent look overcomes the threatening appearance of the masks that can be a feasible way of reducing the social trauma caused by the current CoV disease-19 pandemic. In this study, we investigated the effects of nozzle temperature on the optical, mechanical, and morphological and filtration properties of the nanoporous filter.
