Metallic polyaniline

Fig. VII-1 shows a schematic of the structure of a polymer LED and a picture of a thin film flexible polymer LED seven-segment display. The bottom electrode of this display was made by spin-cas ting a layer of metallic polyaniline onto a flexible plastic substrate [69]. Polyaniline was chosen as the electrode material because it is flexible, conducts current, and is transparent to visible light. The emissive layer of the display was fo med by spin casting a layer of MEH-PPV over the polyaniline. The top electrodes were formed by evaporating calcium through a patterned shadow mask. Since the conductivity of undoped emissive polymers is relatively low, it was not necessary to pattern the polymer or the bottom electrode to prevent current spreading between neighboring pixels.

Fig. 4.1 shows a schematic of the structure of a polymer LED. A photo of a thin-film flexible seven-segment display fabricated from a semiconducting polymer is shown in Fig. 4.2. The bottom electrode (the anode) of this flexible display was made by spin-casting a layer of metallic polyaniline onto a flexible plastic substrate [12].

More recent works have been performed with metallic polyaniline as CSA doped polyaniline [60]. Substantially different properties occur with this class of material. Large negative dielectric constant is obtained in the case of CSA doped polyaniline when evaporated from meta-cresol. A classical behaviour is obtained if evaporation takes place with chloroform (Figure 8.28)... [Pg.404]

Applications like corrosion protection by ennobling and passivation, and manufacture of printed circuit board surfaces composed of the organic metal polyaniline (Ormecon) are based exclusively on this unique set of properties and use most of the properties in parallel. Here, this new materials class is able to offer a performance that cannot be matched by any other material or by another conductive polymer. [Pg.1072]

This product, as well as the already established Ormecon CSN and the recently introduced CSN FF, are based on the organic metal polyaniline, which is responsible for a completely different deposition mechanism and tin layer structure. This is due to the fact that the organic metal not only passivates the copper (and later the tin), but also exclusively forms Cu(I) cations and transfers electrons to the Sn(II) ions for the reduction and deposition, thus acting as a catalyst. [Pg.1091]
