Triple-A-COAT will develop antimicrobial, antifungal and antiviral coatings based on nanocellulose that has been modified to enhance its activity against pathogens:
These nature-inspired approaches have minimal risk of resistance development, and avoid the safety issues of nanoparticles.
We are working with the three main types of nanocellulose. From the multiple materials and approaches we have available, we will develop a technology platform including:
Our test case for the project is the public transport environment. Considering surfaces found in a bus, we will develop coatings that can be applied on metal, plastic, glass and seat fabric.
At each stage of development, we will test the coatings for their antimicrobial or antiviral activity, and their other performance parameters (durability, uniformity, appearance etc). We have defined several technical objectives or benchmarks for the performance of the coatings.
The final stage of the project will involve scale-up of production, and a practical demonstration of the three best performing coatings in a bus simulation booth constructed by our partner Van Hool at the campus of KU Leuven.
The project lasts 4 years from September 2022 until August 2026. The project activities are organised in 7 work packages:
