Conducting polymer functionalized multi-walled carbon nanotubes nanocomposites: Optical properties and morphological characteristics

• Functionalized CNTs (PSCNTs) have been used as acceptor material.
• Homogeneous dispersion of PSCNTs in MEH-PPV polymer.
• Comparison between CNTs and PSCNTs properties.

Donor/acceptor heterostructures formed by a donor conducting polymer and carbon nanotubes as acceptor materials are elaborated. Carbon nanotubes (CNTs) have been functionalized with polystyrene. A huge potential for functionalized CNTs for an effective charge transfer was shown. Moreover, optical properties have been correlated with morphological characteristics. We conclude that there is a relationship between the morphology and the performances of polymer/CNTs bulk heterojunction nanocomposites, integrated as photoactive layer for photovoltaic application.
