Notes:
Fresh poly(phenylene sulfide) (PPS) fibers have pleated surface morphology and banded texture. These structural features are similar to those of poly(phenylene terephthalamide) fiber (Kevlar), whereas some unique morphologies were observed for the long-term stored PPS fibers, which have not been found with liquid crystalline polymer fibers including Kevlar. The long-term stored PPS fibers show a decreased Tg and a decreased onset temperature of melting, compared with their fresh counterparts, which is attributed to stress relaxation and resulting disorientation in the amorphous region of the fibers. Combination of the observed typical morphologies with polarized optical microscopy and X-ray diffraction analysis suggests that PPS possesses liquid crystalline nature.
