Description: Using natural cellulosic fibers as fillers for biodegradable polymers can result in fully biodegradable composites. Biodegradable composites were prepared using nanofibrillated cellulose (NFC) as the reinforcement and poly (3-hydroxybutyrate-co-3-hydroxyvalerate, PHBV) as the polymer matrix. The objective of this study was to determine how various additives (i.e., blending PHBV with chain extender (CE) and/or Ecovio—a commercially available PLA/PBAT blend) affect the mechanical properties of injection molded PHBV/NFC nanocomposites. Tensile test bars of PHBV/NFC nanocomposites were produced via a novel process involving freeze drying and high-shear followed by injection molding. A three-variable, two-level, full-factorial design was used to investigate the effects and interactions of CE, Ecovio, and NFC content on the mechanical properties of the nanocomposites. At the level investigated, Ecovio had the largest influence of all of the additives studied on the mechanical properties of PHBV. Two significant interactions between variables were also found. The tensile modulus and strength increased slightly with 3% NFC content in neat PHBV but more considerably in PHBV with Ecovio. Moreover, 1 wt% CE increased the tensile modulus of neat PHBV slightly but had no effect on PHBV with NFC or Ecovio.
