摘要:
A method for preparation of an iodoalkylalkoxysilane includes contacting a haloalkylmethoxysilane with an alcohol in the presence of a protic acid to form a haloalkylalkoxysilane. The haloalkylalkoxysilane is contacted with an iodide to form the iodoalkylalkoxysilane. The iodoalkylalkoxysilane can be used as a chemical intermediate in the preparation of functional aryl amine molecules which have application in the formation of thin films for photoreceptors.

A toner process including, for example, mixing a latex with a colorant wherein the latex contains resin and an ionic surfactant, and the colorant contains a surfactant and a colorant; adding a polyaluminum chloride; affecting aggregation by heating; adding a chelating component and a base wherein the base increases the pH of the formed aggregates; heating the resulting mixture to accomplish coalescence; and isolating the toner.
摘要:
Exemplary embodiments provide nanotube-containing coating compositions and methods for making and using the coating compositions. In an exemplary embodiment, the coating composition can include a plurality of nanotubes (e.g., carbon nanotubes (CNTs)) dispersed stably and uniformly in a polymer matrix containing fluoropolymers. The coating composition can further include stabilizers to allow a stable and/or uniform dispersion of the plurality of nanotubes in the fluoropolymers. The nanotube coating composition can be coated on an article surface to improve mechanical robustness, and electrical and thermal conductivity of the coated article. The coated article can be used as, for example, a fuser member, a fixing member, a pressure roller, or a release agent donor member in an electrostatographic printing machine or process.

Exemplary embodiments provide coating compositions having pseudo-fluorine surface and methods for processing and using the coating compositions. The coating composition can include, for example, a plurality of fluorine-containing resin fillers and a plurality of nanotubes (e.g., carbon nanotubes (CNTs)) dispersed in a polymer matrix that contains, e.g., one or more cross-linked polymers. The fluorine-containing resin fillers can provide a pseudo-fluorine surface for a low surface energy of the coating composition. The nanotubes can be dispersed in the polymer matrix to provide an improved mechanical robustness of the coating composition. The coating composition can be coated on a member surface, wherein the coated member can be, for example, a fuser member, a fixing member, a pressure roller, or a release agent donor member, used in an electrostatographic printing device or process.
摘要:
An electronic device, such as a thin-film transistor, includes a substrate and a dielectric layer formed from a dielectric composition. The dielectric composition includes a dielectric material, a crosslinking agent, and an infrared absorbing agent. In particular embodiments, the dielectric material comprises a lower-k dielectric material and a higher-k dielectric polymer. When deposited, the lower-k dielectric material and the higher-k dielectric material form separate phases. The infrared absorbing agent allows the dielectric composition to attain a temperature that is significantly greater than the temperature attained by the substrate during curing. This difference in temperature allows the dielectric layer to be cured at relatively high temperatures and/or shorter time periods, permitting the selection of lower-cost substrate materials that would otherwise be deformed by the curing of the dielectric layer.
