Self-Assembly of Block Copolymers in Supercritical Fluids, U.S.-Turkey Cooperative Research

产品描述：该奖项是为了支持斯托尼布鲁克的纽约州立大学化学系的Ben Chu博士和土耳其伊斯坦布尔的Bogazici大学聚合物研究中心的Burak Erman博士的合作研究。 在这项研究中，两位科学家将结合现代分析方法（例如同步辐射超小角X射线散射）和现代计算机模拟技术（例如分子动力学），以更深入地了解嵌段共聚物在超临界流体中自组装行为的结构/性能关系。 采用短链二嵌段F3 C（CF2）m-（CH 2）nCH 3在超临界CO2中进行自组装，通过计算机模拟、实验和建模研究了聚合物浓度、总链长、链长比、温度和CO2压力对自组装行为的影响。 范围：该奖项是部分资助访问美国私人侦探。和一名美国研究生访问博阿齐奇大学，以及土耳其科学家访问纽约州立大学斯托尼布鲁克。 Erman博士将向土耳其政府寻求资金，以支付在该国的部分费用。 该项目带来了两个非常有经验的科学家在聚合物化学领域合作了解聚合过程。 预期的结果可以帮助改进聚合物的生产，而不使用对环境有害的有机硫。 该项目还允许在土耳其最好的技术大学之一的国际环境中培训美国研究生。 该项目非常符合国际方案司的目标。

Description: This award is to support collaborative research by Dr. Ben Chu, Chemistry Department, State University of New York at Stony Brook and Dr. Burak Erman, Polymer Research Center, Bogazici University in Istanbul, Turkey. In this research the two scientists will use a combination of modern analytical methods (e.g synchrotron ultrasmall angle x-ray scattering) and modern computer simulation techniques (e.g. molecular dynamics) to provide deeper understanding of the structure/property relationship for the self-assembly behavior of block copolymers in supercritical fluids. It is proposed to use short-chain diblocks of F3C(CF2)m-(CH2)nCH3 in supercritical Carbon dioxide and to investigate the self-assembly behavior as a function of polymer concentration, total chain length, chain length ratio, temperature and CO2 pressure by means of computer simulations, experiment and modeling. Scope: This award is to partially fund visits by the U.S. P.I. and a U.S. graduate student to Bogazici University, and the visit of the Turkish scientist to SUNY,Stony Brook. Dr. Erman will be seeking funds from the Turkish Government to cover part of the costs in that country. The project brings two very experienced scientists in the field of polymer chemistry to collaborate on understanding the process of polymerization. The expected results could help improve the production of polymers without the use of organic sulfurs which are an environmental hazard. The project also allows for the training of a U.S. graduate student in an international setting at one of Turkey's best technical universities. The project fits well with the objectives of the Division of International Programs.
