Figures

Image of FIG. 1.
FIG. 1.

The (001) x-ray diffraction peak observed at room temperature for (a) unrecrystallized and (b) recrystallized-irradiated copolymer films, with doses of 60, 85, and . The data from unirradiated samples are also plotted for comparison. (Note: curves have been shifted vertically to avoid overlap and different scales are used for the Y axes, as indicated.)

Image of FIG. 2.
FIG. 2.

The (200,110) x-ray diffraction peak observed at room temperature for unrecrystallized- (“1”) and recrystallized- (“2”) irradiated copolymer films. The irradiation doses are indicated in the figure.

FIG. 3.

Three-peak fitting curves for the (200, 110) peak of samples with doses of : (a) unrecrystallized- and (b) recrystallized-irradiated copolymer films. The solid line is the measured curve, and the dashed lines are the fitted curves.

FIG. 4.

FTIR absorption bands for the unrecrystallized- (dashed line) and recrystallized- (solid line) irradiated copolymer samples with irradiation dose of .

Image of FIG. 5.
FIG. 5.

DSC data for unrecrystallized- (solid lines) and recrystallized- (dashed lines) irradiated samples with different doses (as marked on each trace). The heating rate was . (Note: Different scales are used for the axes, as indicated.)

Image of FIG. 6.
FIG. 6.

Dielectric constant and loss at different frequencies vs temperature for recrystallized- and unrecrystallized- irradiated copolymer films. The frequencies used were 0.1, 1, 10, and . The frequency increases from top to bottom in the dielectric constant curves (dashed lines) and from bottom to top for the dielectric loss curves (solid lines).

FIG. 7.

Polarization loops for recrystallized- (thick lines) and unrecrystallized- (thin lines) irradiated copolymer films irradiated with different doses: 60 (a), 85 (b), and (c).
