Study on the degradation behavior and mechanism of Poly ...
2020-2-3u2002·u2002Poly(lactic acid) (PLA) was modified by ferric chloride (FeCl 3). • FeCl 3 accelerates the degradation of PLA by nearly 10 times. • The chemical reaction between Fe 3+ and ester carbonyl promotes the degradation. • PLA changes from a crystalline polymer to a non-crystalline polymer. • FeCl 3 significantly reduces the thermal stability ...
