The development of new biodegradable composites with superior properties is an attractive approach to develop environmentally friendly materials with new potential applications. In this work, we prepared and characterized PHB filaments with different concentrations of ZnO particles (from 0.5 up to 16 wt%) to evaluate this mixture's effect on the physico-chemical, thermal properties, and morphological biofilament characteristics. The FTIR and Raman results indicated a possible chemical interaction between the ZnO and PHB, altering the helical polymeric and crystalline structure. The ZnO particles increased the composites' thermal stability, mainly at higher filler contents, confirmed

Acetylated‐cellulose nanostructures (CNS) were used as reinforcing agent to develop poly(butylene adipate‐co‐terephthalate)—PBAT—nanocomposites with 1, 3, 5, and 10 wt% of modified and nonmodified nanoparticles through solvent casting. This study explains the interactions between the reactive groups CNS and PBAT interact and the influence of this interaction in the mechanical and thermal properties of the composites. The nonmodified CNS showed a noncontinuous increase in the PBAT stiffness, due to the low interaction between the reinforcement and the matrix and low CNS dispersion. The best results were obtained to acetylated CNS due to the intermolecular interactions between the acetyl groups and the polymer chains. Probably the acetyl groups interfered in the atomic vibration relative to the functional groups of the matrix, which is indicative of the interaction and enhancement of the internal cohesion of the components.
