By incorporating inorganic constituents into these materials, we can bring about the best of both worlds in terms of new properties that might not be offered by either material alone.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cbr \/\u003E\r\nThis thesis presents a processing theory created from experimental measurements\u0026nbsp;to allow precise control of vapor phase infiltration (VPI) used to create new organic-inorganic hybrid materials. VPI works by allowing metalorganic precursors commonly used in chemical vapor deposition to diffuse into polymers and react with polymer functional groups or co-reactants at low processing temperatures (below 200 Celsius). This process can transform nanometers to microns of polymer into hybrid material. While several research groups have explored various materials properties of VPI-modified polymers, the research community still does not understand the exact processing kinetics and thermodynamics of VPI. By using \u003Cem\u003Eex situ\u003C\/em\u003E and \u003Cem\u003Ein situ\u003C\/em\u003E characterization techniques, we have calculated energy parameters for VPI processing kinetics and thermodynamics for the classic trimethylaluminum and poly(methyl methacrylate) system. This thesis also presents new properties in the hybrid materials including chemical stability and water absorption that can give more insight into what the materials can transform into through VPI.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Hybrid Organic-Inorganic Materials Synthesized via Vapor Phase Infiltration\u0022"}],"uid":"27707","created_gmt":"2018-07-26 15:14:11","changed_gmt":"2018-07-26 15:14:11","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2018-08-30T16:30:00-04:00","event_time_end":"2018-08-30T18:30:00-04:00","event_time_end_last":"2018-08-30T18:30:00-04:00","gmt_time_start":"2018-08-30 20:30:00","gmt_time_end":"2018-08-30 22:30:00","gmt_time_end_last":"2018-08-30 22:30:00","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":""}}}
