Abstract: A method is providing for forming a substantially uniaxially-oriented, high content cellulose nanocrystals film. The method includes providing a plant-biomass-bsed suspension of cellulose nanocrystals and altering the pH of the cellulose nanocrystals to a substantially neutral pH. The suspension is sheared at a shearing rate. The method further includes orienting the cellulose nanocrystals in a substantially axial direction and removing water from the sheared cellulose nanocrystals suspension. As a result, a substantially uniaxially-oriented cellulose nanocrystals film is formed.

Keywords: cellulose nanocrystaline film, uniaxially-oriented, high content, plant-biomass-based, pH (neutral), shear, cellulose nanocrystals (CNC), industry, highly oriented, high-strength composites, manufacturing
