Development of Nanofiber Reinforced Double Layered Cabin Air Filter Using Novel Upward Mass Production Electrospinning Set Up

Recently, numerous researchers are interested in the development of new air filter because of air pollution caused by rapid industrialization and urbanization. The major concerns in developing air filters are: pressure drop and filtration efficiency which are considered significant. As the pressure drop increases, the energy consumption becomes high. In this study, we developed a novel air filter (polyurethane fiber mat) for nano size filtration using a mass production electrospinning, which is expected to enhance filtration efficiency and pressure drop effects. To determine the optimal electrospinning conditions for filter efficiency, various concentrations (8, 10, 12 wt/wt%) of thermoplastic polyurethane were prepared and employed. Scanning electron microscope (SEM) and Fourier transform infrared spectroscopy (FT-IR) were used for fiber characterization, and finally, efficiency test was conducted to evaluate the filter performance of developed nanofiber-based air filter. From this study, it could be concluded that optimization by adjusting the polymer concentration and electrospinning operating condition was the best efficient alternative method to fabricate nano-fibrous air filter system with improved filtration performance.

近来，由于快速的工业化和城市化造成的空气污染，许多研究人员对新型空气滤清器的开发感兴趣。开发空气过滤器的主要问题是：压降和过滤效率被认为是重要的。随着压降的增加，能量消耗变高。在这项研究中，我们开发了一种新型的空气过滤器（聚氨酯纤维毡），用于通过大规模生产静电纺丝技术进行纳米级过滤，有望增强过滤效率和压降效果。为了确定用于过滤器效率的最佳电纺条件，制备并采用了各种浓度（8、10、12 wt / wt％）的热塑性聚氨酯。利用扫描电子显微镜（SEM）和傅里叶变换红外光谱（FT-IR）进行纤维表征，最后进行效率测试，以评价开发的纳米纤维基空气过滤器的过滤性能。从这项研究中可以得出结论，通过调节聚合物浓度和静电纺丝操作条件进行优化是制造具有改善的过滤性能的纳米纤维空气过滤器系统的最佳有效替代方法。
