Self-Sanitization in a Silk Nanofibrous Network for Biodegradable PM_0.3 Filters with In Situ Joule Heating.

ABSTRACT: In the contemporary way of life, face masks are crucial in managing disease transmission and battling air pollution. However, two key challenges, self-sanitization and biodegradation of face masks, need immediate attention, prompting the development of innovative solutions for the future. In this study, we present a novel approach that combines controlled acid hydrolysis and mechanical chopping to synthesize a silk nanofibrous network (SNN) seamlessly integrated with a wearable stainless steel mesh, resulting in the fabrication of self-sanitizable face masks. The distinct architecture of face masks showcases remarkable filtration efficiencies of 91.4, 95.4, and 98.3% for PM_0.3, PM_0.5, and PM_1.0, respectively, while maintaining a comfortable level of breatha
