Nanoporous flexographic printing : fundamentals, applications and scale-up

Printing of ultrathin layers of polymeric and colloidal inks is critical for the manufacturing of electronics on non-conventional substrates such as paper and polymer films, for applications such as smart packaging, asset tracking, and photovoltaics. Among conventional printing processes, flexography is a scalable, high-speed direct printing method, yet its resolution is limited by squeeze-out of ink between the non-porous stamp and substrate and by dewetting of the deposited ink film. Broadly, there remains an important need for improved printing technologies for ultrathin (~0.1 [mu[m or smaller) and fine features (~ [mu]m resolution) to advance printed electronics technology. In flexographic printing, it was recently demonstrated that significantly finer printed feature dimensions can be achieved when nanoporous stamps are used instead of traditional non-porous polymer stamps.
