ABSTRACT Cellulose nanocrystal (CNCs)‐reinforced poly(lactic acid) (PLA) nanocomposites were prepared using twin screw extrusion followed by injection molding. Masterbatch approach was used to achieve more efficient dispersion of CNCs in PLA matrix. Modified (b‐CNCs) benzoic acid as a nontoxic material through green esterification method solvent‐free technique. Transmission electron microscopy images did not exhibit significant differences the structure b‐CNCs compared with unmodified CNCs....
