Controllably conductive polymer compositions may be used in electrophotographic imaging developing systems, such as scavengeless or hybrid scavengeless systems or liquid image development systems. The conductive polymer compositions includes a charge-transporting material (particularly a charge-transporting, thiophene-containing polymer or an inert elastomeric polymer, such as a butadiene- or isoprene-based copolymer or an aromatic polyether-based polyurethane elastomer, that additionally comprises charge transport molecules) and a dopant capable of accepting electrons from the charge-transporting material. The invention also relates to an electrophotographic printing machine, a developing apparatus, and a coated transport member, an intermediate transfer belt, and a hybrid compliant photoreceptor comprising a composition of the invention.

Controllably conductive polymer compositions for development systems

A coated donor roll comprised of a core with a coating thereover comprised of a photolysis reaction product of a charge transporting polymer and a photo acid compound.

Developing apparatus including a coated developer roller

A process for minimizing or avoiding the corrosion of thermal ink jet heater components by the coating thereof with polycrystalline diamond.

Coating processes with a polycrystalline diamond passivation layer

A method of forming a patterned, poly-crystalline diamond film on a substrate is disclosed. First, a photoresist layer is applied to a substrate. A diamond powder layer is formed on the photoresist layer either through spray-coating, dip-coating, spin-coating using a diamond-powder suspension, and the like. The photoresist layer is exposed to electromagnetic radiation through a mask either before or after the diamond powder layer is applied. Then, the photoresist layer is developed, after which the substrate is heated causing the photoresist layer to carbonize. The substrate is exposed to a mixture of hydrogen-containing and carbon-containing gases which are decomposed in a processing apparatus. Hydrogen in this gas mixture etches away at the carbonized photoresist layer leaving behind the patterned diamond powder layer. Carbon in these carbon-containing gases combines with the diamond particles in the diamond powder layer to form diamond structures on the substrate.

Method for the direct patterning of diamond films

An imaging member comprised of a supporting substrate, a photogenerator layer optionally dispersed in a resin binder, and a charge transport layer comprised of a fullerene or fullerenes optionally dispersed in a resin binder.

Photoconductive imaging members with a fullerene compound

An ink composition which comprises an aqueous or organic liquid vehicle, and as a colorant a fullerene, or a mixture of fullerenes.

Liquid ink compositions

A thin film transistor in which a source electrode is electrically isolated from a drain electrode and a gate electrode. The gate electrode is formed on one surface of an electrically insulating layer. A semiconducting layer is formed on the other surface of the electrically insulating layer. The semiconducting layer has a charge carrier mobility of at least 1 cm.sup.2 /V-sec. and is made from a polycrystalline diamond layer. The source electrode and the drain electrode are formed on one surface of the polycrystalline diamond layer. The other surface of the polycrystalline diamond layer is in integral contact with the other surface of the electrically insulating layer.

Thin film transistor

A process for the preparation of continuous polycrystalline diamond films which comprises applying to a substrate diamond powder in an amount of from about one particle per ten square microns to about 10 particles per square micron with an average particle diameter of from about 0.1 to about 0.4 micron; heating the resulting powdered substrate subsequent to incorporation in a processing apparatus; introducing a mixture of gases into the chamber, which gases provide a supply of carbon and hydrogen; and decomposing the gas mixture.
