    Background

    Treating frequently touched surfaces with antimicrobial, antifungal and antiviral coatings could help reduce the spread of infectious diseases in busy environments.

    Antimicrobial coatings

    Alongside COVID-19, we face a continual challenge from other serious transmittable diseases, including influenza, hospital superbugs such as MRSA and Candida albicans, and stomach infections.

    Why nanomaterials?

    Nanomaterials are any kind of material that is structured at the scale between 1 and 100 nanometers, in at least one of their dimensions. They are much smaller than can be seen with the naked eye, but larger than individual molecules.

    Sustainability

    We consider substitute materials for coatings that do not come from fossil fuels, are biodegradable and safer for the environment. Bio-based materials obtained from sustainable sources can contribute to all these goals.

    Our approach

    Project Plan

    Project Plan

    Triple-A-COAT will develop antimicrobial, antifungal and antiviral coatings based on nanocellulose that has been modified to enhance its activity against pathogens.

    Nanocellulose

    Nanocellulose

    In Triple-A-COAT we work with the three main forms of nanocellulose, produced by three of our industry partners, with diverse structures and properties.

    Antimicrobial functionalities

    Antimicrobial functionalities

    Triple-A-COAT partners KU Leuven, Stellenbosch University and Imperial College have developed exciting new approaches to combat pathogens. This research will now be developed further in Triple-A-COAT to create antimicrobial, antifungal and antiviral nanocellulose based coatings.

    Coatings knowhow

    Coatings knowhow

    The project will investigate how to improve the adhesion of nanocellulose to four model surface materials: metal, plastic, glass and seat fabric. To enhance adhesion, various “linker” compounds will be tested.

    Life cycle assessment

    Life cycle assessment

    In Triple-A-COAT, life cycle assessment specialists 2.-0 LCA consultants will assess the environmental impact of our coatings in terms of their production, use and disposal, and compare their environmental performance with competing products.

    Triple-A-COAT project reaches end of year 1

    The Triple-A-COAT project has now reached the end of its first year! Project partners met together at EAWAG in Zurich, September 13th-14th 2023, hosted by our Swiss partner SuSoS AG. Triple-A-COAT is working with 3 types of nanocellulose, and several different approaches for antimicrobial functionalisation and coating adhesion to surfaces. This gives us many different parameters to play with, so we can develop the best performing antimicrobial …
