ARPLAE project publishes details of novel rheometry technique to improve the quality of printed electronics

 

"The use of functional materials, such as those employed in printed electronics applications, relies on the ability to reproducibly formulate materials that display complex rheological properties. These materials must then be processed under complex flow conditions [such as those found in the printing process]...

There is a need, therefore, for a technique that can facilitate the characterisation of the complex rheological nature of functional materials under flow conditions that can be performed rapidly using minimum sample volumes."

This paper reports the development of a novel rheology technique which meets this need.

The Centre's ARPLAE project addressed fundamental rheological challenges to achieving high-resolution features in the production of functional inks in high-yield contact printing processes. Research, techniques and partnerships from ARPLAE continue to be developed in the flagship project P2CAR.
