Image of FIG. 1.
FIG. 1.

THz spectra of the various UHMWPE samples; refractive indices in the upper panels, and absorption coefficients in the lower panels. (a), (b), and (c) correspond to the virgin UHMWPE samples, the UHMWPE samples doped with 0.1 wt % vitamin E, and the UHMWPE samples with 0.3 wt % vitamin E, respectively. Open and closed circles mean the nonirradiation and the irradiation, respectively. The open and closed circles of panels (b) and (c) almost overlap in the lower panels.

FIG. 2.

Cole–Cole plots of the UHMWPE samples. (a) The virgin UHMWPE sample (open circle), the -irradiated virgin UHMWPE sample (closed circle), the UHMWPE sample doped with 0.1 wt % vitamin E (open square), the -irradiated UHMWPE sample doped with 0.1 wt % vitamin E (closed square), the UHMWPE sample doped with 0.3 wt % vitamin E (open triangle), and the -irradiated UHMWPE sample doped with 0.3 wt % vitamin E (closed triangle). (b) and (c) Enlarged illustrations of (a) for the virgin UHMWPE sample and the -irradiated virgin UHMWPE sample, respectively.

Image of FIG. 3.
FIG. 3.

Difference spectra in density-normalized , , between the -irradiated and corresponding nonirradiated UHMWPE samples. Open circle, closed circle, and open square represent for the virgin UHMWPE samples, the UHMWPE samples doped with 0.1 wt % vitamin E, and the UHMWPE samples doped with 0.3 wt % vitamin E, respectively.
