제목 Lamellar thickness of poly(ethylene oxide) film crystallized from gel state
초록 Lamellar thickness of poly(ethylene oxide) film crystallized from gel state was investigated in terms of the polymer concentrations in solution which produces the gel network under exposure of gamma-ray. Long period of lamellar distance and the thickness of crystalline and amorphous layers in the crystalline films were analyzed from the small angle X-ray scattering patterns. The wide distribution and non-uniformity of the lamellae were also observed in the elongated and the swollen films. Comparing with the chain length between crosslinks, the possible positions of crosslinks in lamellar stacks were discussed. The results reveal the influence of the crosslinks on crystallization and demonstrate the phenomena at a conjunction of crosslinking and crystalline state.
