Modern society requires electronic devices to be more \u003Cbr \/\u003Eflexible and environmental friendly, which makes cellulose as a good \u003Cbr \/\u003Ecandidate for the next generation of green electronics. However, lots of \u003Cbr \/\u003Eresearches employed \u201cpaper-like\u201d petroleum-based polymers to fabricate \u003Cbr \/\u003Eelectronics rather than using real cellulose paper. Cellulose, as a \u003Cbr \/\u003Erepresentative of environmental friendly materials, caught into people\u2019s \u003Cbr \/\u003Eattention because of its sustainable nature, ease of functionality, \u003Cbr \/\u003Eflexibility and tunable surface properties, etc. There are some general \u003Cbr \/\u003Echallenges about using cellulose for electronics, such as its \u003Cbr \/\u003Enon-conductivity, porosity and roughness, but these features can be taken \u003Cbr \/\u003Eadvantages of on certain occasions. This thesis focuses on the study of \u003Cbr \/\u003Ecellulose-based electronic devices by chemical or physical modification of \u003Cbr \/\u003Emicrofibrillated cellulose (MFC). Particularly, three electronic devices \u003Cbr \/\u003Ewere fabricated, including ionic diodes, electric double layer \u003Cbr \/\u003Esupercapacitors, pseudocapacitors. In addition, a rational design of \u003Cbr \/\u003Edye-sensitized solar cell was investigated, although it was not directly \u003Cbr \/\u003Ecellulose-based, it led the way to the next generation of cellulose-based \u003Cbr \/\u003Esolar cells. The extraordinary physical and chemical properties of MFC were \u003Cbr \/\u003Esuccessfully leveled in those devices, in addition, inspiring and effective \u003Cbr \/\u003Efabrication methods were proposed and carried out to solve the major \u003Cbr \/\u003Eproblems faced by paper-based electronics, such as conductivity, \u003Cbr \/\u003Eflexibility, packaging and designs.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Fabrication of Electronic Devices For Energy Storage And Harvest"}],"uid":"28077","created_gmt":"2014-10-23 13:32:10","changed_gmt":"2016-10-08 02:09:54","author":"Danielle Ramirez","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2014-11-05T14:00:00-05:00","event_time_end":"2014-11-05T16:00:00-05:00","event_time_end_last":"2014-11-05T16:00:00-05:00","gmt_time_start":"2014-11-05 19:00:00","gmt_time_end":"2014-11-05 21:00:00","gmt_time_end_last":"2014-11-05 21:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"1808","name":"graduate students"},{"id":"100811","name":"Phd Defense"},{"id":"5171","name":"PTFE"}],"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":""}}}
