Abstract
Nanocomposites of polyaniline loaded with different weight-fractions of double-wall carbon nanotubes were fabricated by in situ polymerizations of the polyaniline in the presence of double-wall carbon nanotubes. The composition of the nanocomposites is examined by X-ray diffraction and scanning electron microscopy techniques. The functionality of the synthesized composites was studied by electrical conductivity and fluorescence analyses. The dc conductivity of polyaniline was increased by introducing 2.5 wt% of DWCNTs into polyaniline matrix. The fluorescence emission from the double-wall carbon nanotubes/polyaniline showed a broad emission range in the visible region between 350 and 560 nm with appreciable enhancement in the intensity at 434 nm.
