The development described provides methods of producing functionalized cellulose in a one-step acid treatment process and of using the cellulose so derived to make composite polymer materials. The composite materials may include mixtures of the acid treated cellulose, functionalized cellulose polymers, including but not limited to cellulose acetate, cellulose butyrate, cellulose propionate, methyl cellulose, and ethyl cellulose, biobased and/or biodegradable polymers, impact modifying agents, and other components such as nucleating agents and pigments. The composite materials formed possess thermomechanical properties that differ from those of similar polymer composites made using prior art. In particular, the composite and nanocomposite materials are characterized by increased heat distortion temperatures and improved impact strengths. |
