Printed, flexible and even stretchable electronics have potential as low-cost alternatives for devices in industries ranging from energy to health care to security.  However, their successful commercialization relies not only on the design and development of sustainable, robust and reliable materials chemistries, but also the solution-based processes used for printing devices and circuits.  Studies have shown that device performance depend critically on semiconductor alignment at many length scales. Further, materials’ nano- through meso-structure can be manipulated in solution prior to thin-film formation.  Recently, it has been demonstrated that even with no perturbations, polymer semiconductors self-assemble in solution over time.  Observations surrounding the behavior of these materials suggest that requisite macroscopic long-range order required for high performance devices may be achieved through process optimization which utilizes knowledge associated with materials structure-process-property relationships. This presentation will provide an overview of how structure-process-property relationship considerations can be applied to several classes of advanced electronic materials. The resulting fundamental insights will enable realization of robust and reproducible semiconducting solutions for flexible electronics applications.
