Abstract

The indisputable and widespread Coronavirus disease (COVID-19) has caused tremendous social life changes. COVID-19 has expeditiously taken the lives of innocent individuals. Combined with social distancing and quintessential hygiene habits, one of the key protective strategies to reduce the coronavirus spread and return to the norm is to wear facemasks. Objectives: The purpose of this study is to experimentally characterize a commercial K95 and disposable nonsurgical masks (NSM) with electrospun nanofiber membrane used as a filtration unit in a facial mask. The goal is to enhance the user's thermal comfort as heat generated from prolonged use causes fatigue, skin rash, and discomfort to an individual. The masks were modified using polycaprolactone nanofiber mesh to provide better thermal comfort and protection against coronavirus and compare the results with the commercially used KN95 and disposable masks. The IR Transmittance rate of the filtration layers was investigated using the Attenuated Total Reflection (ATR). The higher IR transmittance shows an excellent cooling effect of body temperature for PCL nanofibers (85%) compared to nonsurgical (25%) and K95 (35%) masks. The mechanical strengths of the commercial and modified filtration layer show PCL membrane has adequate strength to withstand maximum inhale and exhale respiratory pressure. Therefore, face masks with better thermal management will be helpful for prolonged use and enhanced comfort. The future goal of this work is to study composite layer-based finite element simulation with transport properties and modify the mask with a nanofiber-based face mask.
