Preliminary surface testing was performed in combination with cure profile. In addition, dendron-PDMS hybrid behavior was probed via several physical characterization techniques. Ultimately, this work illustrates the first reported QAC bis-MPA type dendrons and their biocidal activity, the first reported dendron-PDMS hybrid copolymers and their behavior and preliminary studies displaying their potential use as surface active additives in Sylgard 184.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"\u0022Quaternary Ammonium Cation Bis-MPA Dendron PDMS Hybrid Copolymers: Synthesis, Characterization, Behavior and Functional Use as Macromolecular Additives in Sylgard 184\u201d"}],"uid":"27707","created_gmt":"2022-05-16 15:21:30","changed_gmt":"2022-05-16 15:21:30","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2022-05-18T13:00:00-04:00","event_time_end":"2022-05-18T15:00:00-04:00","event_time_end_last":"2022-05-18T15:00:00-04:00","gmt_time_start":"2022-05-18 17:00:00","gmt_time_end":"2022-05-18 19:00:00","gmt_time_end_last":"2022-05-18 19:00:00","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":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
