Poly(3,4-ethylenedioxythiophene):Poly(styrenesulfonate) (PEDOT:PSS) has been recognized as the most useful conductive films in recent years. However, the flexibility and the weather stability were considered as the drawbacks in the application of these conductive films. In this research, an innovative approach was presented by using the Poly(styrenesulfonate)-Poly(n-Butyl acrylate) (PSS-PBA) latex as a template to prepare a series of flexible conductive aqueous dispersion and the corresponding thin films, PEDOT:PSS-PBA. The optoelectronic properties of the flexible conductive films, such as surface resistance and transparency, were investigated. The bending test for the PEDOT:PSS-PBA films was undergone by measuring the surface resistance increment with the bending times. It was found that the flexible conductive films, PEDOT:PSS-PBA exhibited more stable conductivity than pure PEDOT:PSS conductive films after bending the specimens 200 times.
