PLA films with improved flexibility properties by using maleinized cottonseed oil

This work assesses the potential of maleinized cottonseed oil – MCSO as plasticizer in poly(lactic acid) – PLA films with improved ductile behaviour. The effects of MCSO are compared with commercially available maleinized oil, i.e. maleinized linseed oil – MLO in terms of mechanical, thermal and barrier properties, as well as morphology changes. Plasticized PLA formulations were obtained with a maleinized oil content in the 0–10 wt% range....
