Large polymer extended-chain crystals have an important role that cannot be replaced in the study on low dimensional systems of physics. However, the small size of polymer extended-chain crystals that formerly had to be obtained through a long time confined their effect. Adding 10%(mass fraction) PC to PET, we obtained plenty of polymer extended-chain single crystals with C axis thickness exceeding 100 μm during the study on the high-pressure crystallization behaviors of PET/PC blends with a self-made piston-cylinder apparatus. For the first time, scanning electron microscope was employed to analyze them in a deep-going way. Large extended-chain crystals with various morphologies were observed by SEM, i.e. perfect extended-chain crystals, extended-chain crystals fractured along or perpendicular to C axis, extended-chain crystals with cohesive fracture surfaces, different wedge-shaped extended-chain crystals on different fracture surfaces and bending extended-chain crystals. Some mechanisms were also put forward for the formation of the observed large crystals.
