However, conventional packaging materials are designed within a linear economy framework, often leading to persistent environmental challenges due to limited end-of-life management. Addressing this issue requires the development of sustainable polymers that balance high-performance properties with recyclability, including chemical depolymerization, biodegradation, and the use of bio-derived feedstocks.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EThis thesis presents a comprehensive polymer informatics workflow that integrates computational simulations, predictive machine learning models, and digital polymerization reactions to accelerate the design and discovery of sustainable packaging materials. High-throughput molecular dynamics and Monte Carlo simulations generate low-fidelity data, which, when combined with experimental measurements, improve predictive accuracy across key properties such as gas and water permeability, mechanical strength, and thermal stability. Multi-task learning models enable reliable extrapolation to unexplored chemical spaces, guiding the screening of millions of hypothetical polymers generated through virtual forward synthesis.\u003Cbr\u003E\u003Cbr\u003EThe workflow is applied to ring-opening polymerization (ROP) polymers, resulting in the identification of promising candidates and the experimental validation of one polymer, poly(dioxanone), which exhibits strong water barrier performance. A Python-based package was also developed to standardize simulation workflows and facilitate broader adoption within the scientific community. Overall, this work demonstrates the potential of polymer informatics to accelerate the discovery of high-performance, environmentally responsible packaging materials, forging a path toward a more sustainable future by closing the loop on polymer design and addressing critical environmental challenges.\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003E\u003Cstrong\u003EPolymer\u0026nbsp;informatics\u0026nbsp;advancements\u0026nbsp;to\u0026nbsp;accelerate\u0026nbsp;the design\u0026nbsp;of\u0026nbsp;sustainable\u0026nbsp;packaging\u0026nbsp;materials\u003C\/strong\u003E\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Polymer informatics advancements to accelerate the design of sustainable packaging materials"}],"uid":"27707","created_gmt":"2025-11-06 19:54:12","changed_gmt":"2025-11-06 19:55:18","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2025-11-19T10:00:00-05:00","event_time_end":"2025-11-19T12:00:00-05:00","event_time_end_last":"2025-11-19T12:00:00-05:00","gmt_time_start":"2025-11-19 15:00:00","gmt_time_end":"2025-11-19 17:00:00","gmt_time_end_last":"2025-11-19 17:00:00","rrule":null,"timezone":"America\/New_York"},"location":"MRDC Room 3515","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":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
