Preparation and Characterization of Nanocompocite Conducting Polymers (PANI-DBSA/MWNCT)
Abstract
Nanocomposite conducting polymers ,PANI-DBSA/MWNCT were prepared by adding different weight ratios of c-MWNCT (1,2,3,5 ) % to Polyaniline (PANI) doped with DBSA( PANI-DBSA ). Structural characteristics of nanofibers composites and the formation of functional group were measured by . X-ray diffraction (XRD) and FT-IR spectroscopy. X-Ray Diffraction showed crystalline peaks of the Nanocomposites PANI-DBSA /MWNCT. FT-IR spectra confirmed the change of MWNCT to c-MWNCT by strong acids ,and PANI doped with DBSA. The Morphology and diameters for the nanofibers composites were studied by Atomic Force Microscope (AFM) and scanning electron microscope(SEM). The average diameter for nanofiber composites was about 117 nm (at 1 wt% MWCNT concentration ) and 90.47 nm (at 5wt% MWCNT concentration) found from AFM. SEM also show the homogeneous coating of PANI-DBSA onto the MWNCNT indicating that carbon nanotubes were well dispersed in conducting polymer matrix
