摘要：
High-speed spun poly(ethylene terephthalate) (PET) fibers that had higher crystallinity, largercrystallite sizes, and lower birefringence than ordinarily spun PET showed higher penetrability to Fe-3(CO)(12) and its derivatives in supercritical carbon dioxide fluid at a temperature of 50 degrees C-80 degrees C and a pressure of 18.2-19.3 MPa. The sizes of the channels caused by the fibrillation of PET fibers in supercritical CO2 fluid influenced the penetrability of these organometallic compounds.
