Aerosolization Suppression and Nanoparticulate Filtration by Means of Innovative Polymer Usage

The dissertation titled "Aerosolization Suppression and Nanoparticulate Filtration by Means of Innovative Polymer Usage" presents novel strategies to address critical challenges in public health and industrial filtration, particularly focusing on aerosolization and nanoparticle filtration. The research aims to suppress aerosolization at three key stages: at the source, during airborne transition, and upon droplet impact with solid surfaces. These efforts are particularly relevant in healthcare environments, such as dental procedures, where aerosolization of fluids poses significant risks for pathogen transmission, including viruses like SARS-CoV-2. A specific solution for aerosolization suppression has been developed and patented, which involves modifying the physical behavior of fluids used in dental tools, significantly reducing the risk of airborne contamination. Another central focus of this work is the development of advanced nanofiber-based filtration membranes to efficiently capture nano-scale airborne particles. Nanoparticle filtration is vital for improving air quality and controlling environmental pollution. Using innovative polymers, such as pH-responsive poly(acrylic acid) (PAA) and thermo-responsive poly(N-isopropylacrylamide) (PNIPAM), the dissertation explores dual-responsive filtration systems that adapt to environmental changes. These materials were synthesized through electrospinning techniques and subjected to comprehensive experimental evaluation, including tests for stability, mass loss, and performance under varying pH and temperature conditions. Furthermore, the research investigates the behavior of droplets impacting dielectric surfaces, exploring how electric forces can be harnessed to control droplet dynamics and enhance surface wettability. This study has important implications for coating and spraying technologies, demonstrating that by manipulating droplet behavior, material interactions can be more precisely controlled, optimizing filtration and surface treatment processes. Through these combined efforts in aerosol suppression, nanoparticulate filtration, and droplet impact studies, this dissertation contributes to advancing technologies in public health, environmental protection, and industrial applications. The innovative use of polymer-based materials and electrospinning techniques has the potential to offer significant improvements in both air and water filtration systems, providing a dynamic and adaptable solution for modern challenges.
