Single-walled carbon nanotubes (SWCNTs) coatings on film have been investigated as transparent conductive films (TCFs). In order to fully utilize the properties of SWCNTs in practical applications, efficient dispersion of SWCNTs is firstly required. Among many methods, non-covalent functionalization using polymeric dispersants has advantage of obtaining exfoliated SWCNTs with high aspect ratio. However the residual polymer reduce the electrical properties after TCF fabrication. Therefore post treatment to remove unnecessary residue is inevitable for high conductivity. Here, poly[2-(dimethylamino)ethyl methacrylate]-co-polystyrene] (p(DMAEMA-co-St)) was used as a polymeric dispersant for SWCNT dispersion. SWCNTs/polymer coatings on glass substrates, were prepared by spin-coating method. Furthermore, thermal post treatments of TCFs were carried out to enhance their conductivity. The effects of thermal treatment were analyzed by SEM, Raman spectroscopy, AFM and XPS. |
