Upgrading Cellulose Filaments for Incorporation into Value-added Products

Cellulose filaments (CFs) are recently-developed materials derived from wood pulp, consisting of very long, thin cellulosic strands. These filaments can be incorporated into a number of high-value non-traditional products, such as thermoset and thermoplastic composites, and can be used as rheology modifiers in fluids such as paints and various industrial fluids. However, the ‘raw’ filaments require upgrading before they can be used for these non-traditional applications. This project will involve developing scalable processes for tailoring filament properties to prepare them for subsequent incorporation into these value-added products. Specifically, proof-of-concept laboratory-scale processes for upgrading nanocellulose will be assessed and tested for their applicability to upgrading CFs, as well as for their near-term cost-effectiveness and scalability. This research will provide Performance BioFilaments with state-of-the-art technical information on cellulose filament upgrading technologies, providing a basis for equipment selection and engineering decisions as the company proceeds towards the commercialization of this innovative new product.
