Patent number: 10294567Abstract: Aqueous dispersions of artificially synthesized, mussel-inspired polyopamine nanoparticles were inkjet printed on flexible polyethylene terephthalate (PET) substrates. Narrow line patterns (4 ?m in width) of polydopamine resulted due to evaporatively driven transport (coffee ring effect). The printed patterns were metallized via a site-selective Cu electroless plating process at a controlled temperature (30° C.) for varied bath times. The lowest electrical resistivity value of the plated Cu lines was about 6 times greater than the bulk resistivity of Cu. This process presents an industrially viable way to fabricate Cu conductive fine patterns for flexible electronics at low temperature, and low cost.Type: GrantFiled: December 10, 2015Date of Patent: May 21, 2019Assignee: The Research Foundation for the State University of New YorkInventors: Siyuan Ma, Liang Liu, Vadim Bromberg, Timothy Singler

Publication number: 20190001654Abstract: Touchscreen computing devices are often assembled by applying an adhesive to an interface perimeter between a cover glass and a chassis. Occasionally, a device is de-bonded to troubleshoot errors in the functionality of the device. The adhesive often is resistant to releasing the bond between the cover glass and a chassis by mechanical force and the cover glass may be damaged during disassembly. Passive and/or active de-bonding aids facilitate transfer of thermal energy to the adhesive in a manner that avoids or minimizes the transfer of thermal energy to heat-sensitive components of the device.Type: ApplicationFiled: June 30, 2017Publication date: January 3, 2019Inventors: James Michael BONICATTO, Han LI, David John HUSTON, James David HOLBERY, Siyuan MA
