Nanocellulose-Electrochromic Composite Thin Films

Cellulose is a renewable and biodegradable material that is largely available from forest resources in Quebec and Canada. Recent advances in nanotechnology have allowed us to extract cellulose at the nanoscale, decomposing it into nano-building blocks that have the potential of generating a whole new class of nanocellulose-based materials. Our project would be the first aiming at developing novel cellulose-based electrochromic (smart) composites. These composites can be prepared by combining electrochromic (EC) nanomaterials with hydrophilic biocompatible cellulose. An original deposition method for composite thin films is being proposed. These novel materials and devices will make use of the remarkable properties of both nanocellulose and inorganic EC nanoparticles. Potential industrial applications include flexible displays, flexible electronics, smart papers and smart glazings.
