IMR: Acquisition of Modern Gel Permeation Chromatography Instrumentation for the Butler Polymer Research Laboratory

该奖项来自于材料研究仪器项目，支持佛罗里达大学获得一种凝胶渗透色谱（GPC）仪器，该仪器配备了四个探测器和高温能力，可以为许多正在开发的新聚合物提供分子量信息。这些项目涵盖了传统聚烯烃的建模，共轭和低氧化电位的电活性聚合物，以及检查高度组织的核壳聚合物的结构。该仪器基于Waters高温GPC，能够在高达150摄氏度的温度下进行测量，并拥有一系列检测系统（UV/Vis，折射率，光散射和差分粘度测定），由三家供应商组装：Waters公司，Wyatt技术公司和Viscotek公司。一些NSF发起或资助的聚合物科学研究将受益于使用该仪器。此外，40-50名本科生、研究生（包括两名NSF研究生研究员）和博士后将在巴特勒实验室接受该仪器的培训。来自大分子科学与工程中心（特别是材料科学）其他部门的研究人员将使用该设施。此外，杜兰教授领导着一个与法国有密切联系的NSF/REU网站，每个教职员工都通过这个网站指导REU的学生。佛罗里达大学巴特勒聚合物研究实验室的研究小组将获得仪器来测量他们研究的大聚合物分子的大小（所谓的分子量）。该仪器是一种凝胶渗透色谱（GPC）仪器，将完全配备现代研究能力。这些项目涵盖了传统聚烯烃（如聚乙烯）的研究，共轭和导电聚合物的研究，以及聚合物胶体结构的研究。该仪器将基于Waters公司的高温GPC，该GPC拥有一系列由三家供应商组装的检测系统：Waters公司、Wyatt技术公司和Viscotek公司。NSF发起或资助的研究将受益于使用拟议的仪器，包括制造新塑料的项目，用于药物释放的聚合物，用于制造全有机显示器的聚合物，以及用于生物和化学传感器的聚合物。此外，40-50名本科生、研究生（包括两名NSF研究生研究员）和博士后将在巴特勒实验室接受有关该仪器的培训。来自大分子科学与工程中心（特别是材料科学）其他部门的研究人员将使用该设施。此外，杜兰教授领导着一个与法国有密切联系的NSF/REU网站，每个教职员工都通过这个网站指导REU的学生。

This award from the Instrumentation for Materials Research program supports the University of Florida with the acquisition of of a gel permeation chromatography (GPC) instrument equipped with four detectors and high temperature capability to provide molecular weight information on a number of new polymers being developed. The projects span the range of modeling conventional polyolefins, to conjugated and electroactive polymers with especially low oxidation potentials, to examining the structure of highly organized core-shell polymers. The instrument is based on a Waters high temperature GPC, capable of making measurements at temperatures up to 150 degrees C, and possessing an array of detection systems (UV/Vis, refractive index, light scattering, and differential viscometry) assembled from three vendors: Waters Corporation, Wyatt Technology Corporation, and Viscotek Corporation. Several NSF initiated or funded research in polymers science will benefit from using the instrument. In addition 40-50 undergraduate students, graduate students (including two NSF Graduate Research Fellows) and postdocs present at any one time in the Butler Laboratory will attain training on this instrumentation. Researchers from other Departments in the Center for Macromolecular Science and Engineering (especially Materials Science) will use the facility. Further, Professor Duran leads an NSF/REU site with strong ties to France, and each of the faculty members directs REU students through this.%%%The research team that operates out of the Butler Polymer Research Laboratory at the University of Florida, will acquire instrumentation to measure the size (so called molecular weight) of the large polymeric molecules with which they work. The instrument is a gel permeation chromatography (GPC) instrument and will be fully equipped for modern research capability. The projects span studies of conventional polyolefins (e.g. polyethylene), to conjugated and electrically conducting polymers, to examining the structure of polymers for colloids. The instrument will be based on a Waters high temperature GPC possessing an array of detection systems assembled from three vendors: Waters Corporation, Wyatt Technology Corporation, and Viscotek Corporation. NSF initiated or funded research that will benefit from using the proposed instrument includes projects to make new plastics, polymers for drug release, polymers to make all-organic displays, and polymers for biological and chemical sensors. In addition 40-50 undergraduate students, graduate students (including two NSF Graduate Research Fellows) and postdocs present at any one time in the Butler Laboratory who will recieve training on this instrumentation. Researchers from other Departments in the Center for Macromolecular Science and Engineering (especially Materials Science) will use the facility. Further, Professor Duran leads an NSF/REU site with strong ties to France, and each of the faculty members directs REU students through this.
