Abstract: Banded spherulites in bulk crystallization of poly (ethylene oxide)(PEO) are observed with polarizing optical microscopy.The interesting phenomenon is that the concentric bands can still be observed without polars and are assumed to results from the step-growing or spiral-growing of spherulites rather than from the lamellae twisting.The concentric cracks are also observed within every single spherulite together with the bands,which might be meaningful for research and application.
