摘要

•Thermal degradation kinetics of biodegradable polymer blends was evaluated•Kissinger-Akahira-Sunose and Vyazovkin isoconversional methods were applied•The composition and morphology of the blends influenced their thermal behavior•The addition of nanochitin diminished the effective activation energy of the blends•Avrami-Erofeev function was the most probable kinetic mechanism of the systems studied
