ABSTRAK

Polyethylene succinate PESu blend with amorphous polyvinyl phenol PVPh in thin films were investigated on the crystalline spherulites patterns and crystalline lamellar arrangements by using polarized optical microscopic POM and atomic-force microscopy AFM. A total of nine different types of crystalline morphology were identified in the PESuPVPh blend with amorphous contents from 10 to 35 wt. and Tc820182014070 C in ultra-thin film thickness. Multiple types of PESu crystalline morphology at the same crystallization temperature Tc are never seen in neat PESu but only occur in PESuPVPh blend with amorphous PVPh higher than 20 wt.. Crystalline morphology diagrams are summarized to display various spherulite types in the PESuPVPh blend confined in thin films as a function of crystallization temperature and blend composition. Crystallization temperature thicknessspace confinement and presence of interacting amorphous PVPh are the main factors for multiple types of spherulites in the blends partly due to strong interactions via hydrogen bonding between PESu and PVPh and likely extra nucleation capacity from the diffusion interfaces.
