Abstract:

Hybrid materials of multi walled carbon nanotubes-zinc phthalocyanine (MWCNTs-ZnPc) and multi walled carbon nanotubes-aluminum phthalocyanine (MWCNTs-AlPc) have been prepared. MWCNTs were treated with mixture of nitric and sulfuric acid pre to the mixing with phthalocyanines for the de-bundling effect. Hybrid materials have been drop casted onto glass slides and interdigitated electrodes from their solution in dimethylformamide. UV-visible absorption spectroscopy and Fourier Transform Infrared Spectroscopy (FTIR) have revealed the successful hybridization due π-π interaction between MWCNTs and phthalocyanine species. I-V measurements and DC conductivity of the hybrid films has been investigated. The behavior of DC electrical conductivity and the activation energy with the variation of temperature were studied.
