Water-based technology eliminates solvents, odors and need for specialized chemical-handling equipment while reducing VOCs.

Electrochromic inks and films are an intriguing technology for printed electronics applications. In one well-known example, rear-view mirrorsin vehicles use this technology, which shifts color due to a tiny electric current.
There is a critical drawback to electrochromic inks and films, as they are traditionally a solvent-based technology. They are flammable, and the odors that the solvents emit are a major problem for printing and spraying machinery.
Researchers for Dr. John Reynolds’ team at Georgia Institute of Technology recently announced that they have developed water-based electrochromic film inks. Aside from being safer in terms of handling volatile organic chemicals (VOCs), eliminating certain protective equipment would also offer cost savings. The team published its findings in the journal ACS Central Science on Aug. 16, 2017.
