项目摘要

Non-Technical SummaryThe overall goal of this hypothesis-driven research proposal is to prepare cellulose nanomaterials that perform as advanced functional materials. This will be accomplished by utilizing existing feedstocks of nanocellulose, primarily cellulose nanocrystals (CNC), as a platform for the development of a new class of advanced functional nanomaterials. These nanomaterials represent a promising platform for the attachment of specially designed polymer chains to allow the transformation of simple, renewable, and abundant agricultural products into optically and electrically active components that can be used in advanced applications. The research goal entails the following: the researchers will (a) prepare and characterize CNC modified with semiconducting polymers, (b) process the new materials into thin films and gels and gain a detailed understanding of their morphology, (c) demonstrate the advanced properties of these new materials in light-emitting applications by fabricating and testing devices. The fundamental questions answered by this project are applicable to a community of scientists and engineers beyond those directly involved in the synthesis of semiconducting polymers, cellulose, devices and nanofabrication. Adaptation of cellulose nanomaterials as a feedstock in future products could reduce our reliance on ecologically “challenged” raw materials and boost US-based agriculture and biomass production. The project will provide research training and education of a graduate student who will be trained in new synthesis techniques, advanced characterization methods, and learn how to implement nanomaterials into actual industrial fabrication processes. Technical SummaryThe overall goal of this hypothesis-driven research proposal is to prepare cellulose nanomaterials that perform as advanced functional materials. This will be accomplished by utilizing existing feedstocks of nanocellulose, primarily cellulose nanocrystals (CNC), as a platform for the development of a new class of nanomaterials. These nanomaterials represent a promising platform for the attachment of semiconducting polymer moieties to allow the transformation of simple, renewable, and abundant hydrocarbons to optically and electrically active components that can be used in advanced applications. The goal will be accomplished through a project involving (a) preparation and characterization of CNC modified with semiconducting polymers, (b) processing the new materials into thin films and gels and gaining an understanding of their morphology, and (c) studying the advanced properties of these new materials for electroluminescence applications by fabricating and testing PLEO and LEEC devices. The project will provide research training and education of a graduate student and contribute to enhancing diversity and exploration of commercial potential for these new materials.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
非技术摘要本假设驱动的研究提案的总体目标是制备作为先进功能材料的纤维素纳米材料。这将通过利用现有的纳米纤维素原料,主要是纤维素纳米晶体(CNC),作为开发新型先进功能纳米材料的平台来实现。这些纳米材料代表了一个很有前途的平台,用于连接专门设计的聚合物链,使简单,可再生和丰富的农产品转化为可用于先进应用的光学和电学活性成分。研究目标包括以下内容:研究人员将(a)制备和表征用半导体聚合物改性的CNC,(B)将新材料加工成薄膜和凝胶,并详细了解其形态,(c)通过制造和测试设备来展示这些新材料在发光应用中的先进性能。该项目所回答的基本问题适用于直接参与半导体聚合物,纤维素,器件和纳米纤维素合成的科学家和工程师社区。将纤维素纳米材料作为未来产品的原料,可以减少我们对生态“挑战”原材料的依赖,并促进美国农业和生物质生产。该项目将为研究生提供研究培训和教育,他们将接受新的合成技术,先进的表征方法的培训,并学习如何将纳米材料应用于实际的工业制造过程。 本研究的总体目标是制备纤维素纳米材料,作为先进的功能材料。这将通过利用现有的纳米纤维素原料,主要是纤维素纳米晶体(CNC),作为开发新一类纳米材料的平台来实现。这些纳米材料代表了一个有前途的平台,用于连接半导体聚合物部分,以允许将简单,可再生和丰富的碳氢化合物转化为可用于先进应用的光学和电学活性成分。该目标将通过一个项目来实现,该项目涉及(a)用半导体聚合物改性的CNC的制备和表征,(B)将新材料加工成薄膜和凝胶并了解其形态,以及(c)通过制造和测试PLEO和LEEC器件来研究这些新材料用于电致发光应用的先进性能。该项目将为研究生提供研究培训和教育,并有助于提高这些新材料的多样性和商业潜力的探索。该奖项反映了NSF的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
