A comprehensive study on shape memory behavior of PEG plasticized PLA/TPU bio-blends

[Display omitted] •The shape recovery ratios increased with increasing TPU content in the blends.•The decreasing molecular weight of PEG maximized the shape recovery values.•The maximum total recovery was obtained at 60 °C for 20/80 PLA/TPU blends.•The shape recovery ratios improved from 45% to over...
