Impact of Chitosan Incorporation on PBAT Composite: Thermal, Viscoelastic, Mechanical, and Morphological Properties

Journal of Applied Polymer Science, EarlyView.
The abstract explains the impact of various concentrations of chitosan on PBAT composite. Indeed, the composite is produced at increasing concentrations of chitosan (10%, 20%, and 30%). The decrease in the tensile strength with increased conc. of chitosan was recorded. Furthermore, the same impact was recorded for TGA analysis.
