Crystallization and melting behavior of poly(ε-caprolactone) under physical confinement

[[abstract]]©2005 ACS - The crystallization and melting behavior of Poly(εcaprolactone) (PCL), were studied in a physically confined system using differential scanning calorimetry (DSC). Macrophase-separation and macro-phase separated morphology were identified in the self-assembly blends. The crystallization rate of PCL was found to be strongly affected by the phase-separated morphology, and the effective confinement on crystallization occured while the size of lamellae-like confinement goes below submicrometer. Recognizable melting depression was found for PCL under confinement, whereas significant decrease on relative crystallinity was observed for PCL chains crystallized at higher temperature.[[fileno]]2020111010023[[department]]化學工程學
