The proposed research addresses this issue by introducing variable macromolecular architecture, functionality, and environmental conditions into the assembly of PEs and PILs. The general hypothesis of the research is that branched macromolecular architecture with multiple functionalities can be exploited to mediate the organization of PEs and PILs and guide their assembly into pre-programmed complex morphologies with multifunctional responsive behavior.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe ultimate goal of the research is to understand and control the assembly of branched PEs and PILs and corresponding morphologies and properties. Accordingly, the first task aims to investigate the role of chain architecture and functional composition on the assembly, interfacial behavior, and resulting morphologies of branched polyelectrolytes and poly(ionic liquid)s. In the second task, we will unravel the role of environmental parameters, such as solvents and substrates on the assembly of branched PEs and PILs to develop truly dynamic nanostructures. We will use ionic liquids as solvents and ionogels as dynamic substrates. The conformations, microstructure and morphology of branched PEs and PILs will be evaluated in conjunction to physical properties including mechanical and ion transport properties. Finally, using the mechanisms of organization of branched PEs and PILs studied in previous tasks, functional PE nanocomposites with nanocellulose will be developed in forms of ionogels with remarkable mechanical and ion dynamic properties.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThis work will inspire the design of polymer nanostructures with pre-programmed complex morphologies with multifunctional responsive behavior. This work will help to establish a systematic, transformative understanding, and construction of component-structure-property relationships for the branched PEs and PILs. The development of functional PE and PIL nanocomposites with enhanced mechanical performance and conductivity close to that of pure ionic liquids will meet the challenging requirements of materials in energy storage and conversion applications.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Responsive Nanostructure Morphologies through Dynamic Assembly of Branched Functional Polymers"}],"uid":"27707","created_gmt":"2020-07-08 13:39:51","changed_gmt":"2020-07-08 13:39:51","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2020-07-09T11:30:00-04:00","event_time_end":"2020-07-09T13:30:00-04:00","event_time_end_last":"2020-07-09T13:30:00-04:00","gmt_time_start":"2020-07-09 15:30:00","gmt_time_end":"2020-07-09 17:30:00","gmt_time_end_last":"2020-07-09 17:30:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"174045","name":"Graduate students"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
