Cellulose nanocrystals are bio-based materials derived from forest products that have shown remarkable ability to enhance the physical and chemical properties of a wide range of products. They are non-toxic, biodegradable, and offer a safer and more environmentally benign alternative to other reinforcing additives. This project will assess the capability of cellulose nanocrystals to enhance the properties of two large volume commercial products, water-based coatings (e.g. paints, sealants) and polylactide films. Water-based coatings, also known as latexes, provide an environmentally friendly alternative to solvent-based coatings that emit VOCs (volatile organic compounds) into the atmosphere. Polylactide is a bio-based polymer gaining increasing popularity as a substitute for petroleum-based polymers. If the properties of water-based coatings and polylactide films can be improved by incorporation of cellulose nanocrystals, then less of the products would be required for a given application thereby further reducing their carbon footprint and environmental impact. Researchers from three universities (University of British Columbia, University of Ottawa, and Queen's University) will work with three industry partners, including Anomera Inc., BASF Canada and BC Research Inc. to develop products with enhanced properties resulting from addition of cellulose nanocrystals. The water-based coatings and bioplastic nanocomposites containing cellulose nanocrystals will have significant social, environmental, and economic impacts on the forest, chemical and manufacturing industries in Canada.
