Pascale Champagne: Research

Bioproducts from Renewables - Nanocrystalline Cellulose

In a collaborative project with Dr. Michael Cunningham (ORC in Green Chemistry and Engineering) in the Department of Chemical Engineering at Queen’s University, Dr. Ralph Whitney in the Department of Chemistry at Queen’s University and Woodbridge Foam sponsored by the ArboraNano business-led NCE, the use of a novel chemical approach to modify cellulose with ATRP to create a new polymer - polyurethane interpenetrating network as a hybrid material that will have properties that neither the polymer or polyurethane could provide on their own. In this work the use of ATRP polymer chemistry to selectively surface initiate nanocrystalline cellulose to which a synthetic polymer will be grafted forming a grafted hybrid co-polymer is being investigated. Next, the ATRP grafting process will be initiated in a polyurathane solution, forming an interpenetrating network creating a chemical platform for the generation of new hybrid materials from renewables for the automotive industry. These new materials will be characterized and further tested for their physical/chemical properties, robustness, stability, potential to penetrate new or existing markets.
