The present invention is drawn to compositions and methods of generating epoxide group-functionalized latex particulates in a liquid suspension, as well as compositions and methods of preparing ink-jet inks. Steps of the methods can include forming an emulsion including a continuous hydrophilic phase and a discontinuous hydrophobic phase, wherein the discontinuous hydrophobic phase includes a plurality of monomers. The plurality of monomers can comprise epoxide group-forming monomers and support-forming monomers. Other steps include copolymerizing the monomers to form precursor latex particulates dispersed within the hydrophilic phase, and reacting the precursor latex particulates with a base to form epoxide group-functionalized latex particulates. These latex particulates can be used in a wide variety of applications, including in ink-jet ink printing applications.
Abstract:
Langmuir-Blodgett films are provided in which a molecule is chemically bonded with a bottom electrode substrate as part of a crossed wire device comprising two electrodes and a molecular layer therebetween. The molecule, which comprises a switchable moiety and a connecting moiety, is provided with a photolabile capping group attached to the connecting moiety. The photolabile capping group temporarily caps the reactive connecting group of the molecule. The capped molecules are processed to form a LB film on the water-air interface of water. The films are then exposed to UV light. The photolabile capping group decomposes to give back the connecting group, which remains in the water. As the uncapped LB films are transferred to a bottom electrode substrate, the surface of the electrode reacts with the reactive connecting group of the molecule to form a chemically bonded LB layer on the substrate, thereby providing improved LB films.

Pigment-based inks are provided. The inks include a non-polar carrier fluid and pigment particles suspended in the non-polar carrier fluid. The pigment particles have tri-block copolymer grafts. Each tri-block copolymer graft comprises a tri-block copolymer having three portions: an inner block attached to the pigment particle, a middle block, and an outer block, wherein the inner and outer blocks each contain bulky organic groups to help facilitate solubility of the functionalized polymers in the non-polar solvent and to provide steric stabilization of the resulting particle dispersion in the non-polar solvent, and wherein the middle block contains either acidic or basic functionalized side groups that facilitate charging of the pigment particle. A combination of an electronic display and an electronic ink employing the pigment and a process for making the pigment-based inks are also provided.
