Abstract:

The high performance polymer used as a template material would appear adhesion or film in the process of ablation. Poly(aryl ether ketone) containing 90% carboxyl and 10% allyl（PEEK-PCA-90）were prepared by nucleophilic polycondensation, then the PEEK-PCA-90 nanofibers containing chromium ion (PEEK-PCA-90/Cd2+) nanofibers were prepared by electrostatic spinning, the PEEK-PCA-90/Cd2+nanofibers were finally crosslinked under UV irradiation. Finally, the chrome oxide nanofibers were obtained by ablation. After crosslinking, the shape of nanofibers keep good in the process of calcination, there will be no collapse. The molten inorganic particles, which were prepared by the template without crosslinking, appeared severe deformation after calcination, and even became film. Fiber morphology test results showed that CdO nanofiberswere obtainedafter calcination of cross-linked polymer composite fibers, and the structure of CdO nanofibers remains intact, the diameter is uniform. Crosslinked carboxyl poly (aryl ether ketone) can keep good appearance characteristics, playing a very good role of template.
