摘要:
A fuser member comprised of a supporting substrate comprising an outer layer of a volume grafted elastomer, which is a substantially uniform integral interpenetrating network of a hybrid composition of a fluoroelastomer and a polyorganosiloxane, said volume graft having been formed by dehydrofluorination of said fluoroelastomer by a nucleophilic dehydrofluorinating agent, followed by addition polymerization by the addition of an alkene or alkyne functionally terminated polyorganosiloxane and a polymerization initiator; and wherein said outer layer contains a reactive metal oxide in an amount of from about 2 to about 7 weight percent.

Disclosed is an ink jet recording head comprising a plurality of channels, wherein the channels are capable of being filled with ink from an ink supply and wherein the channels terminate in nozzles on one surface of the printhead, the surface being coated with a polyimide-siloxane block copolymer.
摘要:
A process for restoring imaging members, which comprises (1) providing, subsequent to its utilization and removal from an electrophotographic imaging device, an amorphous silicon photoconductive imaging member with a protective overcoating; (2) contacting this member with a fluorine containing composition for an effective time period enabling the removal of the protective layer; (3) washing and drying the surface of the resulting imaging member; and (4) subsequently depositing a protective layer thereover.
摘要:
A layered photoresponsive imaging member comprised of a supporting substrate; an amorphous photoconductive layer and a hole transport layer dispersed in a resinous binder, which layer is formulated from a solution mixture; and wherein the photoconductive layer is prepared by a process which comprises dissolving an inorganic photoconductive component in a solvent, removing the suspended particles therefrom, depositing the resulting solution on the supporting substrate, and subsequently heating the aforementioned member.

Disclosed is an improved process for the preparation of a stable colloidal dispersion of a selenium tellurium alloy, which comprises providing a solution with a polymer therein; adding to the solution a selenium ester and a tellurium ester; and subsequently subjecting the resulting mixture to a reduction reaction by adding thereto a reducing agent whereby there is generated selenium tellurium particles of a diameter of from about 0.01 micron to about 0.3 micron in solution.
摘要:
Chalcogens and chalcogenide alloys of controlled crystal size are prepared by subjecting the esters to a reduction reaction. The esters may be prepared by treating the corresponding oxides of the desired elements with an alcohol or glycol and then in one embodiment, converted into the desired chalcogen alloys by subjecting a solution mixture of the resulting esters to a co-reduction reaction at high temperatures. The resulting chalcogens and chalcogenide alloys are useful for the preparation of xerographic photoconductive compositions.
摘要:
This invention relates to a process for the reclamation of selenium in high purity from scrap alloys which comprises converting the alloy to a mixture of oxides, separating the selenium oxide formed by alcoholic dissolution, followed by treating this solution with a reducing agent, and thereafter separating the selenium product therefrom.
摘要:
This invention is generally directed to an improved process for reclaiming metallic elements in high purity from a source material containing these elements, which comprises providing a source material, converting the source material to mixture of oxides, reacting the oxides with an alcohol resulting in the formation of esters, and metallic oxides, subjecting the esters, subsequent to purification, to a reduction reaction, subsequently converting the metallic oxides to esters by reaction with a diol, and subjecting, subsequent to purification, the resulting esters to a reduction reaction.
摘要:
