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
