| Abstract Scope |
Biobased composites produced from biopolymers reinforced with suitable fillers are an attractive route for producing sustainable materials with mproved and diversified properties for a wider range of applications. In this study, biobased composites based on PBAT/PLA blend (Ecovio®), kraft lignin, and titanium dioxide (TiO2) were prepared. First, using gamma-irradiation at 30 KGy, pristine kraft lignin was modified. Then, the pristine lignin, irradiated lignin, and TiO2 were successfully incorporated into a PBAT/PLA matrix using a typical melt-mixing process with a twin-screw extruder. Filaments produced by extrusion process from neat PBAT/PLA and its biobased composites were used to obtain parts by FDM 3D printing. The biobased composite samples were characterized by tensile tests, SEM, and XRD analysis. According to results the incorporation of a small amount of lignin and TiO2 into PBAT/PLA blend and FDM 3D printing led to obtaining of biobased composites with suitable properties for a wider range of applications. |
