| Outline of Final Research Achievements |
Polymer crystallite having ring-like morphology was obtained which termed “ring-lite” here. The ring-lite consists of the concentrically arranged crystalline and molten regions of a single-component polymer. The ring-lite is one of the consequences of the Gibbs-Thomson effect. On the other hand, a molten ring structure was also obtained. The latter structure was termed “dark-ring”, because it appears like a black circle when observed by polarizing microscope. Contrary to the appearance of ring-lite due to “normal” Gibbs-Thomson effect, the dark-ring was obtained by the inversion of the melting point when a specific heating rate was applied.
The ring-lite and dark-ring have a structure in which the crystalline region and the molten region are reversed. These “artificial” higher order structures of crystalline polymer were obtained by utilizing a non-equilibrium property of the polymeric material.
