Superhydrophobic Surface Modification for Enhanced Fabric Face Masks: The Impact of Varying HDTMS Concentrations

Abstract

The widespread use of disposable surgical masks and N95 respirators has led to concerning environmental pollutions. As a result, there has been a growing demand for fabric face masks that are not only reusable and environmentally friendly, but also effective in preventing virus transmission. However, traditional fabric masks have a drawback: their hydrophilic nature increases the risk of virus transmission. To address this challenge, an innovative solution for achieving superhydrophobic surface on cotton, microfiber, and microfiber blend materials was investigated. The key focus of this investigation revolves around the impact of varying concentration of hexadecyltrimethoxysilane (HDTMS) on the hydrophobicity of different fabrics. Consequently, all cotton fabric samples treated with 5%, 10% and 20% HDTMS concentration exhibit water contact angles (WCA) surpassing 150o , effortlessly achieving a state of superhydrophobicity. The modified cotton and microfiber materials proudly display not only enhanced water repellency but also boast exceptional self-cleaning and stain resistant properties.
