Summary

Two kinds of hybrid PAN/SiO2 sols were prepared via either sols blend or in-situ polymerization, respectively, and their spinnability was investigated. Hydrolysis time (t1) and spinnable time (t2) of both hybrid sols increased with PAN content. The hybrid fibers were characterized with FTIR, DSC, SEM and TG. As evidenced from the FT-IR spectra and DSC measurements, different chemical structures of hybrid fibers were different with CN groups hydrolyzed in the hybrid fibers via in-situ polymerization. SEM measurements showed the interior structures of the hybrid fibers via in-situ polymerization were more homogeneous. TG measurements suggest both of the hybrid fibers show better resistance to heat than pure PAN.
