The project focuses on the targeted functionalization of textiles with catalytically active surface coatings. Based on the known (photo)catalytic, antibacterial and antiviral effects of additives such as titanium dioxide and silver nanoparticles, these are specifically incorporated into formulations and applied to textiles in conventional application processes. This enables, for example, to create effective filter solutions for air.
The concept focuses on base materials, primarily recycled plastics, to which coatings with specific functionalities applied by spray or draw-down processes. These are introduced in optimum quantities by incorporating them into typical base formulations, e.g. of polyurethane. This provides the fabrics with additional functions such as flame retardant, antibacterial, antiviral, mosquito repellent and/or colors and prints.
