Abstract

Particulate matter (PM) pollution has emerged as one of the most serious environmental problems, because of its detrimental impact on the well-being of people. Consequently, the development of a PM removal filter that is both economical and energy-efficient is imperative. This study investigates the fabrication and performance evaluation of biodegradable and sustainable nanofiber membranes composed of waste hemp hurds and polyvinyl alcohol (PVA) for particulate matter PM filtration. The fabrication of the hemp/PVA composite membranes was accomplished via electrospinning, with the hemp hurds powder content ranging from 1 to 20 wt%. A comprehensive analysis was subsequently performed on the morphology, thermal properties, and filtration performance of the resulting membranes. Filtration tests using cigarette smoke revealed exceptional PM removal efficiencies, with the 15 wt% HH/PVA membrane achieving the highest efficiency of 98.74% for PM_2.5 and 98.73% for PM₁₀, alongside a superior quality factor of 0.049 Pa⁻¹. The membranes demonstrated enhanced PM capture due to increased surface roughness and particle collision probability. These findings suggest that hemp-doped membranes are viable eco-friendly alternatives to petroleum-based filters, providing efficient PM filtration with sustainable benefits.

可生物降解和可持续的大麻草/聚乙烯醇复合膜的制备及其在颗粒物过滤中的应用

颗粒物（PM）污染已成为最严重的环境问题之一，因为它对人们的福祉产生了不利影响。因此，开发一种既经济又节能的PM去除过滤器势在必行。研究了由废麻秆和聚乙烯醇（PVA）组成的可降解可持续纳米纤维膜的制备及其性能评价。采用静电纺丝法制备了麻/聚乙烯醇复合膜，麻束粉含量为1% ~ 20%。随后对所得膜的形态、热性能和过滤性能进行了全面的分析。使用香烟烟雾的过滤测试显示出卓越的PM去除效率，15 wt% HH/PVA膜对PM2.5的最高效率为98.74%，对PM10的最高效率为98.73%，同时质量因子为0.049 Pa−1。由于增加了表面粗糙度和粒子碰撞概率，膜表现出增强的PM捕获。这些发现表明，大麻掺杂膜是可行的环保替代品，可以替代石油基过滤器，提供高效的PM过滤和可持续的效益。
