Resumo
This work investigates the incorporation of Vismia guianensis alcoholic extract
(EAVG) into cassava starch, with the aim of improving its bioplastic properties. Cassava
starch was dissolved into distilled water and doped with 0.2%, 0.5%, and 1.0% EAVG under
a temperature controlled at the gelatinization point (∼70 ◦C) and then cast to form bioplastics.
The resulting samples were characterized via attenuated total reflectance/Fourier
transform infrared spectroscopy (ATR/FTIR), thermogravimetric and differential thermal
analysis (TGA-DTA), X-ray diffraction (XRD), scanning electron microscopy/energy
dispersive spectroscopy (SEM/EDS), atomic force microscopy (AFM), and mechanical
essays, providing insights into chemical composition, thermal stability, crystallinity, surface
morphology, and mechanical properties. The results demonstrated that EAVG played an
effective role, enhancing the flexibility and stability of the bioplastic with potential use in
biomedical applications. Moreover, the results also showed significant improvements in mechanical
and thermal properties, suggesting that EAVG is a valuable addition to bioplastics.
Therefore, EAVG presents a pathway for advancing bioplastics with enhanced mechanical,
thermal, and functional characteristics, with the potential for further advancements in
these fields.
