The research objective of this grant is to elucidate the governing parameters that determine the structure and cohesive properties of polymer-grafted particle assemblies and to establish the knowledge base that will enable the efficient molecular-engineering of nanoparticles that are capable to form mechanically robust array structures. The assembly of nanoparticles into array structures is of central importance to the integration of nanoparticle systems into device architectures for applications ranging from photovoltaics to solid state lighting. A major barrier in the scalable production of self-assembled particle array structures is the brittle nature of particle solids that promotes crack formation during the processing. The proposed study will establish a novel methodology to enhance the cohesive interactions between particles by binding of polymeric ligands to nanoparticle surfaces.If successful, the proposed research will provide new opportunities for the facile fabrication of polymer nanocomposites with prescribed microstructure and enhanced performance and fuel a range of transformative technological innovations, for example, in the area of solid state lighting for which alone the market is estimated to grow to $14.3B by 2013. This research grant will enable cross-disciplinary training for one graduate student and several undergraduate students in the critical areas of polymer and nanoscale materials. Collaboration with ongoing programs funded through the National Science Foundation will promote the participation of minority students and underrepresented groups. This research grant will support the teaching of a new course and encompass the development of a teacher workshop on "nanotechnologies for sustainable energy technologies" as well as a new module to "The Science Van" program that is aimed at supporting STEM education in underfunded schools in the Pittsburgh area.

该资助的研究目标是阐明决定聚合物接枝颗粒组装体的结构和内聚性质的控制参数，并建立知识库，以实现能够形成机械坚固的纳米颗粒的高效分子工程阵列结构。 将纳米颗粒组装成阵列结构对于将纳米颗粒系统集成到从光致发光到固态照明的应用的器件架构中至关重要。 自组装颗粒阵列结构的可规模化生产中的主要障碍是颗粒固体的脆性，其在加工期间促进裂纹形成。 拟议的研究将建立一种新的方法，通过将聚合物配体结合到纳米颗粒表面来增强颗粒之间的内聚相互作用。如果成功，拟议的研究将为轻松制造具有规定微观结构和增强性能的聚合物纳米复合材料提供新的机会，并推动一系列变革性技术创新，例如，在固态照明领域，预计到2013年，仅固态照明市场就将增长到143亿美元。 这项研究资助将使一个研究生和几个本科生在聚合物和纳米材料的关键领域的跨学科培训。 与国家科学基金会资助的正在进行的项目合作，将促进少数民族学生和代表性不足的群体的参与。 这项研究补助金将支持一门新课程的教学，并包括开发一个关于“可持续能源技术的纳米技术”的教师研讨会，以及一个新的模块“科学货车”计划，旨在支持匹兹堡地区资金不足的学校的STEM教育。
