摘要： A coating for an ink jet printhead front face, wherein the coating comprises a oleophobic low adhesion coating. When the oleophobic low adhesion coating is disposed on an ink jet printhead front face surface, jetted drops of ultra-violet gel ink or jetted drops of solid ink exhibit a contact angle greater than 45° and a low sliding angle of less than about 30°. In embodiments, the oleophobic low adhesion coating is thermally stable wherein the surface contact angle and sliding angle show little degradation after the coating is subjected to high temperatures in a range between 180° and 320° or thereabout and high pressures in a range between 100 psi and 400 psi or thereabout during printhead fabrication and manufacturing.

摘要： A magnetic ink printer includes an ink collector to remove residual magnetic ink from a printhead face. The ink collector uses a magnetic member to produce a magnetic field that acts on the magnetic ink to remove the ink from the printhead face with little or no wiping of the printhead face. The magnetic ink is collected for possible reuse in the printhead.

摘要： Polymeric materials, including polymers and polymer-composite materials, are useful for a variety of applications including biocidal coatings. Representative examples include a composite of silver salt particles and an ionic polymer. A novel process was developed whereby the counter-ion of an ionic polymer is precipitated as a metal salt, so as to form metal salt nanoparticles or microparticles within a polymer matrix. In other examples, polymers having cross-linkable silicon-containing groups form stable biocidal coatings on various substrates, including textiles. Biocidal activity may arise from silver salt particles (or other biocidal particles), ions (such as biocidal anions), membrane disruption by charged species, or some combination thereof. Further, bromide ions, such as provided by silver bromide particles, may impart fire retardant properties to textile substrates.
