摘要
A synchronization observation was carried out to investigate the growth of PEO spherulites by using a polarizing optical microscope in order to learn the phenomenon of concentric banded stripes occurred during the growth of PEO spherulites.It was found that the concentric banded stripe didn’t come into being until at least two independent PEO-spherulites met each other,the formation of the concentric banded stripes were owing to the tortuosity of the spherulite after colliding with other spherulites.
