摘要:

High-speed spun poly(ethylene terephthalate) (PET) fibers that had higher crystallinity, larger crystallite sizes, and lower birefringence than ordinarily spun PET showed higher penetrability to Fe3(CO)12and its derivatives in supercritical carbon dioxide fluid at a temperature of 50°C–80°C and a pressure of 18.2–19.3 MPa. The sizes of the channels caused by the fibrillation of PET fibers in supercritical CO2fluid influenced the penetrability of these organometallic compounds.
