Flexible, Highly Transparent, and Conductive Poly(3,4-ethylenedioxythiophene)-Polypropylene Composite Films of Nanofibrillar Morphology

Abstract: A novel chemical strategy for fabricating flexible, transparent, and conductive poly(3,4ethylenedioxythiophene) (PEDOT) films with a nanofibrillar morphology by in situ deposition on commercial plastic substrates has been developed. The key points of the strategy include (1) preimplanting surface sulfate groups (SO 4 -) onto the substrate surface by a confined photocatalytic oxidation (CPO) technique, which was critical both for improving the adhesion of the PEDOT with the substrate via static interactions and… Show more

“…As the transmittance of the PEDOT layer nominally follows Beer’s law, it means that transmittance increases with decreasing thickness. However, this typically results in weak electroconductive properties due to less conductive channels in the thinner sample. A combination of good electroconductive properties and transparency could only be achieved in the product with both a thin thickness and well-organized structure . The hard control of the chemical oxidative polymerization and deposition method makes it difficult to overcome this particular trade-off, especially for the natural biomaterial substrates which have more complex surface structure.…”

“…To better understand the effect of the surface structuration, it was first necessary to produce smooth surfaces with this polymer and to determine its wettability (Young's angles θ Y ) . Smooth surfaces of PProDOT‐F 4 were produced at imposed potential (1.47 V vs. SCE) and using a very low deposition charge (1 mC · cm −2 ).…”

“…In order to avoid the processing problem of a PEDOT film, many researchers attempted to convert EDOT monomers to PEDOT films on substrates directly. The explored methods include direct polymerization, , adsorption in polymerizing solution, , chemical vapor deposition (CVD), , vapor phase polymerization (VPP), , and liquid phase depositional polymerization (LPDP). , Of them, CVD and VPP have attracted much attention because they give PEDOT films with high conductivity and transmittance.…”
