There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

In emerging technologies, such as those in the energy sector and electronics industry, the ability to efficiently mass-produce thin film at a desirable rate and cost and of a desired quality is a major challenge. In such fledgling fields, fabrication is primarily done in a laboratory using bench-top production lines, which do not necessarily scale to mass production lines. This discontinuity has prompted research to understand the feasibility of using traditional scalable manufacturing methods to produce thin film rapidly, with minimal waste, and optimal coating uniformity and quality. In this talk, we will explore various coating techniques and the mechanisms that control the quality of the coated film. Specifically, an understanding of defect generation in coated thin film fabricated using roll-to-roll processes, especially slot die extrusion, will be elucidated. The influence of such defects on system performance will be discussed, as it relates to polymer electrolyte membrane fuel cells. Building upon this framework, preliminary results on the development and implementation of a novel hybrid technology that couples printing and extrusion technologies to continuously coat thin film in discrete and non-discrete patterns will be presented.
While the seminar is free, we do ask you to please RSVP here.
