Summary

This chapter reviews cellulose‐based nanocomposites where the nano‐phase component can be cellulose nanofibers or cellulose nanocrystals. The matrix phase can be comprised of cellulose, a cellulose derivative, or more typically a synthetic or bioderived polymer. The cellulose can be derived from many sources with the choice being related to the locality where the composites will be made. The chapter concentrates on processing techniques for the cellulose. Cellulose derivatives are more readily dissolved or processed than cellulose and therefore suited for nanocomposite preparation with available nanoparticles, platelets, and fibers. Cellulose acetate (CA), cellulose acetate—butyrate (CAB), plasticized with triethyl citrate have been extruded into nanocomposites with modified layered clay. Cellulose nanocrystals added and dispersed in a matrix have more perfect structure and molecular orientation. This is because they have survived preparation by selective acid hydrolysis of larger cellulose structures.
