Abstract

In this study, fibrous membranes from recycled-poly(ethylene terephthalate)/silk fibroin (r-PSF) were prepared by electrospinning for filtration applications. The effect of silk fibroin on morphology, fibers diameters, pores size, wettability, chemical structure, thermo-mechanical properties, filtration efficiency, filtration performance, and comfort properties such as air and water vapor permeability was investigated. The filtration efficiency (FE) and quality factor (Q), which represents filtration performance, were calculated from penetration through the membranes using aerosol particles ranging from 120 nm to 2.46 μm. The fiber diameter influenced both FE and Q. However, the basis weight of the membranes has an effect, especially on the FE. The prepared membranes were classified according to EN149, and the most effective was assigned to the class FFP1 and according to EN1822 to the class H13. The impact of silk fibroin on the air permeability was assessed. Furthermore, the antibacterial activity against bacteria and and biocompatibility were evaluated. It is discussed that antibacterial activity depends not only on the type of used materials but also on fibrous membranes' surface wettability. In vitro biocompatibility of the selected samples was studied, and it was proven to be of the non-cytotoxic effect of the keratinocytes (HaCaT) after 48 h of incubation.

摘要

在本研究中，通过静电纺丝制备了用于过滤应用的再生聚对苯二甲酸乙二酯/丝素蛋白（r-PSF）纤维膜。研究了丝素蛋白对形态、纤维直径、孔径、润湿性、化学结构、热机械性能、过滤效率、过滤性能以及诸如透气和透湿性等舒适性能的影响。使用粒径范围为120纳米至2.46微米的气溶胶颗粒，通过穿透膜来计算代表过滤性能的过滤效率（FE）和品质因数（Q）。纤维直径对FE和Q均有影响。然而，膜的定量（克重）也有影响，尤其是对FE。根据EN149对制备的膜进行分类，最有效的被归为FFP1级，根据EN1822则归为H13级。评估了丝素蛋白对透气性的影响。此外，还评估了对细菌的抗菌活性和生物相容性。讨论了抗菌活性不仅取决于所用材料的类型，还取决于纤维膜的表面润湿性。研究了所选样品的体外生物相容性，结果证明在孵育48小时后对角质形成细胞（HaCaT）无细胞毒性作用。
