Multiply Bound Polymer Chains: Novel Chemistry for Improved Interfacial Properties

田纳西大学化学系的Mark D.Dadmun、休斯顿大学的Rigoberto C.Advincula、克莱姆森大学的S.Michael Kilbey、田纳西大学的Jimmy W Mays和犹他大学的Grant D.Smith获得了化学合作研究项目的一项奖励，资金来自化学系、材料研究部和多学科活动办公室。这个多方面的团队将研究一种新的化学过程来修改和控制界面；多结合聚合物链(MBPC)。我们将合成各种结构的聚合物，并利用理论、模拟和实验技术来研究由这些材料制成的MBPC的组装动力学、表面组织、层结构和性能。此外，还将考察MBPC在许多宏观应用中的使用情况。这项多机构、多学科的研究将产生具有所需结构特征和/或赋予固体界面有用特性的边界环的表面。这项研究将产生技术影响，包括改善界面以促进或防止粘着，稳定胶体颗粒，改善多组分聚合物体系，以及改变表面的磨损特性。这项研究计划还将为本科生和研究生提供跨学科的培训基础，并将利用学生交流将学生暴露在社会和文化多样化的环境中。此外，还将在国家实验室进行一些实验，包括国家标准与技术研究所、橡树岭国家实验室和桑迪亚国家实验室。学生将在多用户设施中获得实践经验，并开发下一代中子用户。代表不足的群体将通过多样性工程计划、田纳西州路易斯·斯托克斯少数群体参与联盟和西部联盟扩大学生机会计划参与聚合物研究。此外，公立高中和大专的科学教师将在研究实验室里呆上四周，为这个项目做出贡献，提供接触聚合物和聚合物研究的机会。最后，将开发一个聚合物界面网站。

Mark D. Dadmun, Department of Chemistry, University of Tennessee, Rigoberto C. Advincula, Department of Chemistry, University of Houston, S. Michael Kilbey, Department of Chemistry, Clemson University, Jimmy W Mays, University of Tennessee and Grant D. Smith, University of Utah, are funded with an award from the Collaborative Research in Chemistry Program with funds provided by the Division of Chemistry, the Division of Materials Research and the Office of Multidisciplinary Activities. This multifaceted team will investigate a novel chemical process to modify and control interfaces; multiply bound polymer chains (MBPCs). Well-defined polymers of various architectures will be synthesized, and theory, simulation and experimental techniques utilized to investigate the kinetics of assembly, surface organization, layer structure, and properties of MBPCs made from these materials. Additionally, the use of MBPCs in a number of macroscopic applications will be examined. This multiinstitution, multidisciplinary research will produce surfaces with bound loops that have desired structural features and/or confer useful properties on solid interfaces. Technological impacts, including the modifation of interfaces to promote or prevent adhesion, stabilization of colloid particles, improvement of multi-component polymer systems, and altered the wear characteristics of surfaces, will result from this research. This research program will also provide an interdisciplinary training ground for undergraduate and graduate students, and will use student exchanges to expose the students to socially and culturally diverse environments. Also, a number of experiments will be carried out at National Laboratories, including the National Institute of Standards and Technology, Oak Ridge National Laboratory, and Sandia National Laboratory. Students will acquire hands-on experience in a multi-user facility and develop the next-generation of neutron users. The participation of under-represented groups in polymer research will take place through the Engineering in Diversity Program, the Tennessee Louis Stokes Alliance for Minority Participation, and the Western Alliance to Expand Student Opportunities Program. Further, science teachers from public high schools and junior colleges will spend four weeks in research laboratories contributing to this project, providing exposure to polymers and polymer research. Finally, a website for polymer interfaces will be developed.
