Preparation of dendritic and network PANI/silica composite fibers

Dendritic and network PANI fibers with controlled diameters from nanosize to sub-micrometer-size were prepared at room temperature. Conducting polyaniline (PANI)/silica composite fibers were synthesized via a sol-gel progress thereafter. Structural characterization was performed using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). FT-IR and UV-vis were used to verify the incorporation of the silica.
