Non Technical Summary
US Industries are in need of new materials that will provide strength at lower weight, and reduce end-of-use impact on landfills. Cellulose nano-materials as a sustainable and compostable high strength reinforcing material can provide a solutions to needs as diverse as car body panels, ballistic glass, computer cases, and flexible electronics. RWU 4709 has become a preferred supplier of both cellulose nano-crystals and cellulose nano-fibrils. This problem area includes operation and supply of raw materials for collaborating research groups, and research into novel treatments characterizations and applications. Of particular interest in characterization is a problem in validating the strength predictions for cellulose nano-materials. Due to their affinity for water, pure materials produced from CNC and CNF shrink considerably as they dry. The shrinkage introduces flaws in the film or solid and testing is largely a matter of the number of flaws rather than the real strength of the material. The initial goal of this part of the project is to develop methods to produce stress and flaw free films that can be tested to determine the attainable physical strength of these materials.

Objectives Summary
1. Scale up production of cellulose nano-crystals (CNC) and cellulose nano-fibrils (CNF) to small pilot scale to improve access to research materials for scientists needing experimental or small scale demonstration quantities.2. Integrate CNC production concepts into the greater forest products industries, including the paper industry and biorefinery.3. Understand and test for the critical strength characteristics of cellulose nano-materials.
