• Abstract: The development of new biodegradable composites with superior properties isan attractive approach to develop environmentally friendly materials with newpotential applications. In this work, we prepared and characterized PHB fila-ments 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 resultsindicated a possible chemical interaction between the ZnO and PHB, alteringthe helical polymeric and crystalline structure. The ZnO particles increasedthe composites' thermal stability, mainly at higher filler contents, confirmedby Tonset and the thermal resistance index, associated with the interfacebetween the particles and the PHB matrix. Also, DSC results indicated thathigher ZnO contents increased the PHB amorphous characteristic, which facil-itates its use as filaments. The microscopies allowed the evaluation of compos-ites' morphology and indicated good filler dispersion and homogeneity, andthe filament diameters were adequate to the FDM 3D printing technique.SEM-EDS confirmed ZnO presence at filament structure, which probably sta-bilized the PHB matrix during the extrusion process and allowed the printingprocess for the PHB-0.5%ZnO filaments into scaffolds, showing the potentialapplication in additive manufacturing processes. These findings may expandPHB applications combining ZnO properties to develop functional and activematerials for biomedical and packaging applications.
