研究目的
To fabricate nanocomposites from double-wall carbon nanotubes/polyaniline by in situ polymerization of polyaniline in the presence of double-wall carbon nanotubes (DWCNTs) and study their structure and functionality (electric and fluorescence emission).
研究成果
The conduction mechanism in DWCNTs/PANI composites was dominated by the amount of DWCNTs in PANI matrix. Mott’s VRH model indicated the presence of more than one dimensionality charge transfer due to the combination of one dimensional DWCNTs together with three dimensional PANI in one composite. The FL emission from the DWCMTs/PANI composites showed a broad emission range in the blue region with appreciable enhancement in the intensity of emission.
研究不足
The study is limited by the potential for agglomeration and isolated islands of DWCNTs within the polymer matrix, which could affect the homogeneity and connectivity of the composite materials. Additionally, the electrical conductivity and fluorescence properties may be influenced by the dispersion and orientation of DWCNTs in the PANI matrix.
