Direct synthesis of a robust cellulosic composite from cellulose acetate and a nanofibrillated bacterial cellulose sol

Abstract Cellulose nanofibers (CNFs) are potential candidates as environmentally friendly reinforcing fibers, and their compatibilization with plastics has attracted widespread interest. In this study, we developed a simple method to prepare cellulose acetate (CA) composite reinforced by nanofibrillated bacterial (NFBC) directly from an aqueous sol. The key steps of our were the utilization water/organic mixed solvent maintain good dispersion NFBC dissolution CA, along evaporation without significant aggregation NFBC. This technique improved dispersibility in film significantly enhanced its mechanical strength.
