ABSTRACT:
Provided are novel methods for making cellulose nanocomposites, comprising biosynthesis of cellulose fibrils in situ using a growth medium comprising a polymer matrix material, under conditions suitable to provide for dispersion of the fibril throughout the growth medium as the fibrils are being formed to provide a cellulose nanocomposite material or film wherein the cellulose fibrils are highly or uniformly dispersed in the cellulose nanocomposite material, and wherein fibril structure and/or nanocomposite composition is customizable. Certain method aspects further comprise removing or separating the cellulose nanocomposite material or film from the medium, and may further comprise washing the cellulose nanocomposite material or film to remove residual medium. Particular aspects further comprise freeze-drying the cellulose nanocomposite material or film, and/or further comprise forming a molded product using the cellulose nanocomposite material or film. Compositions made by the methods are provided.
