摘要：
Conducting polyaniline-Al2O3 composite nanofibers with varying conductivity was prepared by seeding with Al2O3 nanofibers and oxidative polymerization of aniline. TEM and FESEM demonstrated clearly the nanofibers of PANI-Al2O3 with average diameters of mean diameters of 37-52 nm and lengths of up to pm. The XRD diffractograms indicated that the nanocomposite has the emeraldine structure. The DSC and the FTIR studies showed that the nanocomposite was formed from interaction between the polymer and the Al2O3. The conductivity of the composite decreased with an increase in the Al2O3 content incorporated. (c) 2007 Elsevier B.V All rights reserved.
