Poly(methyl methacrylate) (PMMA)/poly(vinyl pyrrolidone) (PVP) conductive films containing carbon nanotubes (CNTs) were deposited on the poly(ethylene terephthalate) (PET) substrate by solution casting method. CNTs were acid-treated to prevent self-aggregation and improve the dispersity in the polymer resins. The morphology, transparency, and electrical characteristics of the films were measured. As a result, CNTs were highly dispersed in polymer due to the increasing of compatibility between CNTs and polymer by acid treatment, as revealed by SEM and TEM images. Transparency and electrical conductivity of the film were determined as a function of CNT content. Transparency of the films was decreased from 89% to 75%, whereas the electrical conductivity of the films was increased with increasing the CNT content and maximum conductivity was found at 0.05 wt% CNT, due to the large numbers of electron conducting pathway. |
