Some Physical Properties of Plasma Polymerized Fluorocarbons. ... 

Although to-date the emphasis has been on plasma polymerized films produced from hydrocarbon based systems, this trend in more recent times has swung towards fluorocarbons in an attempt to produce polymers of similar properties to conventionally prepared linear fluoropolymers. However, it will become clear from the account to follow that in many respects plasma polymerized fluorocarbons differ significantly from their linear counterparts. It is to the plasma polymerization of organic monomers containing solely carbon and fluorine therefore that we shall devote our attention in this section with only brief references to hydrocarbon and fluorohydrocarbon polymers for comparison purposes.

Gold-doped plasma polymerized fluorocarbons (Au-PPFC) have been most frequently studied Q-8), but numerous other combinations have also been reported (1,2). For the Au-PPFC systems, fc has been found to be - 0.40, at which the films electrical conductivity abruptly... 

The use of ESCA to determine the structure and composition of plasma-polymerized fluorocarbons has been discussed in several recent publications (1-fi).

The first applications proposed for metal/plasma polymer films used their colored appearance. Beale [95] and Wielonski and Beale [146] suggested plasma-polymerized organosilicmn films doped with Au, Cu, and Al as decorative coatings. Biederman [131] mentioned the po bility of large optical filters in the case of gold-doped plasma-polymerized fluorocarbon films. Thurstans et al. [161] examined the posdbility of... 

The effect of gold particles on plasma-polymerized fluorocarbon films was examined by Creasy ef al. Laser ablation of gold-containing films produced ions that were similar to those formed in pyrolysis. This observation suggests that gold particles absorb energy, conductively heat the polymer, and affect the mechanism of the ablation.

There are many other studies of ITO surface modification [277] for the purpose of enhanced hole injection. ITO work function can be changed by treatment with UV-ozone [269, 312, 330, 331], plasma [332-334], acids or bases [335-337], and charge transfer [338] as well as by binding dipolar molecules [339, 340] using organotin (or zirconium) alkox-ides [341-343]. The work function of ITO may be changed by electrostatically controlled self-assembled polymer layers [344-349]. The hole injection was also enhanced by electrochemically prepared thin films [350], p-type doped thin films [351 - 354] and plasma polymerized fluorocarbon films [355].
