PROJECT DETAILS:

Cellulose nanocrystals (CNCs) can be produced cost-effectively from wood fibers derived from Canada’s abundant forest resources. As renewable, biodegradable, and environmentally sustainable nanomaterials, CNCs exhibit a unique combination of properties, including a high specific surface area, outstanding mechanical strength, and a low coefficient of thermal expansion. These characteristics make them attractive for a broad range of applications in aerospace, automotive, microelectronics, cosmetics, pharmaceuticals, coatings, oil and gas, and food industries. However, many of these applications require surface functionalization to tailor the physicochemical properties of CNCs and improve their compatibility with polymer matrices and other host materials.

The proposed collaborative research project exploits the unique capabilities of non-thermal atmospheric-pressure plasmas to develop a versatile, straightforward, environmentally friendly, and cost-effective process for the surface functionalization of CNCs. The plasma-assisted process will enable improved dispersion of CNCs within polymer matrices, leading to the development of a new generation of high-performance nanocomposites. Beyond advancing plasma-based nanocomposite manufacturing, this technology is expected to create new commercial opportunities for our industrial partners, Plasmionique and CelluForce, while contributing to the growth and diversification of Canada’s forest-based bioeconomy.
