The world of flexible and hybrid electronics (FHE) was on display during FLEX 2019, organized by SEMI-FlexTech. One of the keys to FHE is the conductive inks and other materials, from silver inks and nanowires and carbon nanotubes to even more unique materials.
Inks were the topic of FLEX Session 17, and attendees learned about the current state-of-the-art of the industry, as well as what may be coming next. Robert Praino Jr., COO and co-founder, Chasm Advanced Materials, opened the session with “Transparent Conductive Films: Hybrid Material Structures vs. Single Material Composition.”
Praino said that after working on developing single material, Chasm saw there were challenges to be overcome. Creating a hybrid system solved these issues.
“We looked at a new hybrid structure,” Praino noted. “We discovered a ‘vehicle’ as a viscosity modifier, which opened the door to a surfactant-free ink. Silver nanowires (Ag
