Project Description

As Additive Manufacturing technologies advance and printed electronics (PE) applications continue to mature there will constantly be a need to utilize more electronically friendly materials as opposed to the materials that have been traditionally used in printing. Polyimide is one such material that has proved difficult to utilize, particularly via inkjet printing. It is well known that there is a trade off in the jettability of an ink and the molecular weight of a polymer chain, being inversely correlated (i.e. higher molecular weight decreases ability to be jetted reliably). In turn this necessitates the dilution of polymers via solvents to the point where the solids % mass of an ink can be prohibitively low. Alternatively, the molecular chain of the polymer can be shortened, but this can then in turn change bulk material properties in a negative manner.

For these reasons, this project is targeting the synthesis and development of a non-solvent polyimide system that can be inkjet printed onto a substrate and react in situ, thus leaving behind a polymer structure that is more akin to traditionally manufactured structures. In the semiconductor industry, polyimide is commonly applied to silicon wafers via spin coating technology and then developed via photolithography for fine features. This project seeks to simplify this process by reducing material waste, pattern directly via digital fabrication, and completely eliminate all the overhead associated with photolithography (e.g. optical masks, large/expensive tools). It is expected that this project will develop a non-solvent polyimide system that when printed and cured mimics spin on polyimide bulk material properties, both electrical and mechanical. It is also expected that all benefits that come with AM (e.g. digital fabrication, multi-layering, etc.) will be ensured, thus enabling next generation polyimide structures for future applications.
