Developing dry-film antimicrobial coatings from cellulose nanocrystals

This project aims to integrate cellulose nanocrystals into commercial dry-film antimicrobial coating formulations as a replacement for talc. Ideally, the incorporation of CNCs will lead to concurrent improvements in dry-film durability and long-term antimicrobial efficacy without negatively impacting film appearance or functional performance. As necessary, CNC surface modifications will be explored to improve compatibility with current gold-standard industrial formulations. By leveraging expertise at Queen’s University in CNC functionalization and formulation development, this project will advance CNC-based controlled-release technology and create a commercially viable antimicrobial paint formulation that meets the new regulatory challenges in Ontario and Canada. We anticipate that the rational surface modification of CNCs will lead to their optimal integration into commercial dry-film coatings, and will help stabilize and control the release of antimicrobial agents for prolonged effectiveness as compared to industry standards. Specifically, our approach will improve the long-term protection against a broad spectrum of microorganisms, algae, and fungi, and increase coating resistance to environmental wear/degradation (e.g. humidity, UV exposure). This collaboration directly supports Oligomaster’s commercialization strategy, ensuring a scientifically validated, high-performance product ready for market adoption.
