摘要: Abstract Poly (ethylene glycol) (PEG) blended with poly (L-lactic acid) (PLLA) as novel green and sustainable shape-stabilized phase change materials (PCMs) were prepared characterized in this study. The miscibility morphology of the blends played an important role properties PCMs. partial between PEG PLLA resulted suitable latent heat a low leakage percentage typical spherulite structure Maltese cross was examined neat PLLA, observed using polarized optical microscopy. However, addition to led formation ring-banded spherulites due presence altering aggregation twisting lamellae. These crystalline structures can capture liquid (including molten PEG), stabilize shape, prevent leakage. thermal mechanical analysis results indicated that thickness PEG/PLLA not significantly changed during process. 75/25 exhibited appropriate film forming strength. Moreover, differential scanning calorimetry demonstrated largest melting (130.26 J/g), which could have great potential for developing energy storage.
