项目摘要
This 3-year research and education program entails collaboration between Prof. Scott Husson at Clemson University and Dr. Earl Wagener of Tetramer Technologies, L.L.C. (Tetramer) in Pendleton, SC. Our overall goal is to develop fundamental structure-property relationships for perfluorocyclobutyl (PFCB) polymer thin films and use these relationships as the foundation for improved molecular architecture design and production practices of PFCB-based membranes with enhanced resistance to compaction and plasticization by CO2 and hydrocarbons. Tetramer's PFCB polymers are new to the membrane art. They have a significant percentage of fluorine in the backbone and structures designed to increase free volume. No previous plasticization/compaction studies have been performed on these polymers. Partnership with Tetramer will give Clemson researchers access to these promising new membrane polymers. A variety of standard and new to the membrane art analytical techniques are proposed to determine the fundamental structure-property relations for a set of PFCB polymers having a range of molecular architectures. A better understanding of how the structure of the membrane separation layer affects its susceptibility to plasticization/compaction/physical aging would allow better prediction of performance and may lead to new ways to limit their negative impacts. Tetramer plans to use the data generated to determine which mitigation techniques, such more rigid backbones, crosslinking, or even segmenting the architecture, would be most effectively applied to increase their competitive advantages over current commercial products. New knowledge on plasticization and compaction phenomena also will contribute to membrane technology in general. CO2 and hydrocarbon-induced plasticization deteriorates the performance of polymer gas separation membranes. Thus, our effort to suppress its negative effects would have great beneficial impacts. This program will enhance the infrastructure for research and education at Clemson and Tetramer. The PI and his students will gain valuable access to new membrane production and performance testing facilities. Tetramer will extend its in-house research capabilities to understand the fundamental physical changes PFCB polymers undergo during performance testing. Prof. Husson and his students will (1) conduct weekly research meetings, (2) carry out research on membrane preparation and performance testing, and (3) present industrial seminars to be given by Prof. Husson each year. Students in this industry-university collaborative research program will gain exposure to the workings of industry and receive mentoring from industry collaborators, as they perform some of their research at Tetramer. Our work will have immediate commercial relevance. Thus, contributing to the university mission to put research to use in teaching and economic development and advance knowledge on functional membranes, which play a vital role in the US economy. A diverse group of students will be recurited, as Prof. Husson has done successfully throughout his career. This diversity extends to gender, race, disability, academic major, and stage of academic progress. One of the points considered in team member selection will be the contribution to diversity. Our work would provide technical knowledge needed to design molecular architecture and production practices to produce more selective, more permeable, and more robust membranes for CO2 separation from natural gas. A result would be a lower cost operation for natural gas pretreatment. Since natural gas is the fastest growing primary energy source in the world and provides over 20% of all energy used in the US, the economic impact could be tremendous.
这个为期3年的研究和教育计划需要克莱姆森大学的Scott Husson教授和Tetramer Technologies,L.L.C.的Earl Wagener博士之间的合作。我们的总体目标是开发全氟环丁基(PFCB)聚合物薄膜的基本结构-性能关系,并使用这些关系作为改进分子结构设计和生产实践的基础,基于PFCB的膜具有增强的抗压缩性和CO2和碳氢化合物的增塑性。Tetramer的PFCB聚合物是膜领域的新产品。它们在主链和结构中具有显著百分比的氟,旨在增加自由体积。之前未对这些聚合物进行塑化/压实研究。与Tetramer的合作将使克莱姆森的研究人员获得这些有前途的新膜聚合物。提出了各种标准和新的膜艺术分析技术,以确定一组PFCB聚合物具有一系列的分子结构的基本结构-性能关系。更好地了解膜分离层的结构如何影响其对增塑/压实/物理老化的敏感性,将有助于更好地预测性能,并可能找到限制其负面影响的新方法。Tetramer计划使用生成的数据来确定哪些缓解技术,例如更刚性的骨架,交联,甚至分割架构,将最有效地应用于增加其相对于当前商业产品的竞争优势。关于塑化和压实现象的新知识也将有助于膜技术的发展。CO2和碳氢化合物引起的增塑使聚合物气体分离膜的性能恶化。因此,我们努力抑制其负面影响将产生巨大的有益影响。该计划将加强克莱姆森和Tetramer的研究和教育基础设施。PI和他的学生将获得宝贵的访问新的膜生产和性能测试设施。Tetramer将扩展其内部研究能力,以了解PFCB聚合物在性能测试期间发生的基本物理变化。 Husson教授和他的学生将(1)每周举行研究会议,(2)进行膜制备和性能测试的研究,(3)每年由Husson教授举办工业研讨会。在这个行业大学合作研究计划的学生将获得接触到行业的运作,并从行业合作者接受指导,因为他们在Tetramer执行他们的一些研究。我们的工作将立即具有商业意义。因此,有助于大学的使命,把研究用于教学和经济发展和先进的知识功能膜,这在美国经济中发挥着至关重要的作用。一个不同的学生群体将被重复,因为教授胡森在他的职业生涯中已经成功地完成。这种多样性延伸到性别、种族、残疾、学术专业和学术进步阶段。在选择团队成员时考虑的一点是对多样性的贡献。我们的工作将提供设计分子结构和生产实践所需的技术知识,以生产更具选择性,更具渗透性和更坚固的天然气CO2分离膜。结果将是天然气预处理的较低成本操作。由于天然气是世界上增长最快的一次能源,占美国能源使用总量的20%以上,因此经济影响可能是巨大的。
