In VPI, a metalorganic precursor adsorbs to the polymer surface, absorbs within, diffuses throughout, and ultimately becomes entrapped within the polymer bulk through a variety of mechanisms. VPI has demonstrated numerous applications such as the modification of mechanical properties, increase in electrical conductivity, enhanced UV stability, and changes in photoluminescence. Additionally, VPI has been used to create uniquely patterned nanostructures from the infiltration of block copolymers, stain polymer blends for contrast in phase imaging, enhance gravimetric sensing capabilities, and in creating hybrid photovoltaics.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EFrom these property explorations and several fundamental studies, a picture of the relevant thermodynamic and kinetic mechanisms behind VPI has begun to emerge. While these mechanisms are generally understood, their detailed characterization and the derivation of fundamental thermodynamic and kinetic parameters are largely unavailable. Limited work has been conducted determining effective diffusion coefficients in the VPI process, but these investigations must be expanded to additional precursor-polymer systems. Additionally, few studies have been conducted to directly connect underlying inorganic entrapment mechanisms to observed property changes. Finally, few reports exist regarding the durability of these changes in simulated use environments. The proposed work will investigate the fundamental mechanisms behind the VPI process, how they connect to material properties such as solvent stability, and how durable these property changes are for daily use applications.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Vapor Phase Infiltration: Sorption Thermodynamics, Chemical Entrapment Mechanisms, and Hybrid Material Structure-Property Relations\u201d"}],"uid":"27707","created_gmt":"2019-11-25 20:03:16","changed_gmt":"2019-11-25 20:03:16","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2019-12-09T11:00:00-05:00","event_time_end":"2019-12-09T13:00:00-05:00","event_time_end_last":"2019-12-09T13:00:00-05:00","gmt_time_start":"2019-12-09 16:00:00","gmt_time_end":"2019-12-09 18:00:00","gmt_time_end_last":"2019-12-09 18:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"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":""}}}
