High Temperature Size Exclusion Chromatography System for the Development of Soft and Mechanically-Adaptive Electrochemical Transistor Devices
Abstract
*Approved for Public Release*Organic electrochemical transistors (OECTs) are an emerging technology for next-generation bioelectronic devices that provide realtime analysis of the human physiological and mental condition. OECT devices must seamlessly integrate with human tissue for proper function, requiring the device to possess tissue-like softness and stretchability, while also maintaininghigh-performance sensing and computing functions. Novel conjugated polymers of unique molecular design are a critical materials platform to satisfy these demanding systems requirements, and research in the Wang lab is opening up new directions toward the molecular engineering of these novel materials. This proposal is for the acquisition of a high-temperature size exclusion chromatography (HT-SEC) system that is capable of operating using chlorinated mobile phases at high temperatures and is integrated with a multi-angle light scattering detector. This HT-SEC system will enable complete molar mass characterization of novel conjugated polymers that areunder development in the Wang Lab. It is an essential tool required to develop the fundamental structure-property relationships anddesign principles for this new class of polymers, and the characterization data obtained from this HT-SEC system will provide crucial guidance for future material developments. The acquisition of this HT-SEC system will have immediate impact on two current ONR research awards to the Principal Investigator, enabling enhanced research activity in this DoD area of interest now and for years to come. Maintained as part of the Soft Matter Characterization Facility, a share user laboratory, this HT-SEC system will be available to any personnel at the University of Chicago, local universities, and Argonne National Laboratory. Over the course of its useful lifetime, it is anticipated that the placement of this HT-SEC system at UChicago will impact the work of many other principal investigators in the Chicagoregion and will contribute directly to the research education of dozens of graduate students and postdoctoral researchers.
