| 摘 要： | Conductive microfibers with an average diameter of ca. 1.0 mm were prepared by in situ polymerization of aniline, in which poly(vinylchloride-acrylonitrile)(PVC-AN) was used as the filament-material in electrospinning to form precursor microfibers and carry the aniline monomers. Fourier-transform infrared(FTIR) results demonstrated that PANi was successfully polymerized in the microfibers. The morphology of the PVC-AN-PANi microfibers was observed by scanning electron microscopy(SEM). Results of differential scanning calorimetry indicated that the polymer composite of PVC-AN-PANi formed via molecular interactions. Although the conductivity of PVC-AN-PANi microfibers was still limited(2.2 fi 10à8S/cm), this method provided an effective and convenient approach for preparing highly uniform and soft microfibrous electrodes.
