Polymer Emulsion for Thermal Ink Jet System
Abstract:Polymer emulsion is very useful for inkjet inks because it can treat media surface at the same time of printing and improve the print durability and then enlarge the application of inkjet printer. But for the thermal inkjet system, polymer emulsion is likely to make aggregates by heating of the ejection and make serious kogation on the heater. To avoid this thermal problem, heat stable polymer emulsion is necessary.
In this paper, several kinds of polymer emulsion are investigated for thermal inkjet inks and low molecular polyester emulsion, polyacrylamide emulsion, and acrylic polymer emulsion with silicone graft side chain are found to show good heat stability for thermal inkjet systems. Especially, the introduction of silicone graft side chain improves the heat stability of the polymer emulsion with only 10% modification and is favorable for further polymer designing.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
