Abstract

Separation of airborne pollutants such as dust, bacteria, and viruses play an important role in humanitarian health. In this field, acrylic polymer with many properties such as electrospinning capability, thermal resistance, and high chemical resistance is attracting scientific and commercial interests as an active layer for fibrous filter media. The aim of this paper is to utilize low cost, natural resource, biocompatible, and high mechanical strength Halloysite nanotubes (HNTs) for improving filtration efficiency. In this regard, acrylic polymer nanofibers were fabricated by solution electrospinning method on nonwoven support with and without HNTs to fabricate nanocomposite and acrylic membrane. The structure and morphology of membranes were examined by Fourier-transform infrared spectroscopy (FTIR), electron scanning electron microscopy (SEM), and Energy-dispersive X-ray spectroscopy (EDX). Furthermore, the mechanical properties of the samples were analyzed using a single-axis tensile test. Finally, in order to evaluate the filtration efficiency measurement, DOP (dispersed oil particle) were utilized. The results reveal that the nanocomposite membrane has a better performance comparing to the acrylic membrane due to the separation of 95.5% of DOP particles. This layer could be applied as an active layer in N95 face mask.
