摘要建议标题：研讨会CC：非均相聚合物材料的传输行为编号：CBET-0646260主要研究员：罗伯特·H·帕查维斯，研究所：材料研究学会摘要：非均相聚合物材料和复合材料的传输行为研讨会将讨论美国国家科学基金会化学传输系统部门特别感兴趣的各种材料问题。研讨会的学术价值在于，由于它聚焦于特定的主题，研讨会中的各个会议将共同提供一幅关于传输行为(电、热、质量)、独特微结构的影响、基于聚合物基质中纳米级夹杂物的复合材料的新颖表征和制造技术的协同图景。例如，重点讨论导电聚合物复合材料的会议将提供有关化学和微观结构对复合材料性能影响的信息。在设计基于聚合物的EMI屏蔽、传感器和/或静电消散层时，这些信息将是有价值的。其他侧重于聚合物复合材料中热传输的会议将提供有用的信息，以创建具有更好的导热性的特殊涂层，以更快地冷却热表面或制造更高效的电子散热器。集中于质量传输的会议将讨论包装应用的气体屏障、非均质燃料电池膜和新型气体和液体分离膜。例如，最近人们认识到混合基质膜中的界面现象在决定膜性能的过程中起着关键作用。毫无疑问，这些影响在其他异类系统中也是至关重要的。除了侧重于实验研究的会议外，专题讨论会还将包括旨在模拟运输现象的会议。例如，最近的原子模拟对碳纳米管中的传输提供了独特的见解，并推动了用于分离应用的新型碳纳米管/聚合物系统的发展。从更广泛的影响角度来看，上述每个领域的顶级研究人员将发表受邀的演讲，这些演讲将成为每一次会议的支柱。受邀演讲之后，将进行相互关联的演讲，呈现一个共同的主题。本次研讨会的最终目标将是捕捉非均相聚合物材料研究领域的最新发展。鉴于政府、学术界和工业界的浓厚兴趣，希望这次研讨会每年由李女士举办。

Abstract Proposal Title: Symposium CC: Transport Behavior of Heterogeneous Polymeric Materials Number: CBET-0646260 Principal Investigator:Robert H Pachavis, Institution: Materials Research SocietyAbstract:The symposium entitled Transport Behavior of Heterogeneous Polymeric Materials andComposites will discuss a variety of materials issues of particular interest to the ChemicalTransport Systems Division at NSF. The Intellectual Merit of the symposium is that because it is focused on specific themes, the individual sessions in the symposium will together offer a synergistic picture of the transport behavior (electrical, thermal, mass), effects of unique microstructures, novel characterization and fabrication techniques of composites based on nano-scale inclusions in polymer matrices. For example, sessions focused on electrically conductive polymer composites will provide information about the influence of chemistry and microstructure on composite performance. This information will be valuable when designing polymer based EMI shielding, sensors, and/or electrostatic dissipation layers. Other sessions focused on thermal transport in polymer composites will provide information useful for creating special coatings with improved thermal conductivity for faster cooling of hot surfaces or making more efficient heat sinks for electronics. Sessions focused on mass transport will discuss gas barriers for packaging applications, heterogeneous fuel cell membranes and novel gas and liquid separation membranes. For example, it has been realized recently that interfacial phenomena in mixed matrix membranes play a key role in determining the membrane performance. No doubt, these effects are also crucial in other heterogeneous systems. In addition to sessions focused on experimental research, the symposium will also include sessions aimed at modeling of transport phenomena. For example, recent atomistic simulations have offered unique insights on transport in carbon nanotubes and propelled the development of novel carbon nanotube/polymer systems for separation applications.From a Broader Impacts perspective, top researchers in each of the areas just described will give invited talks that will act as anchors for each of the sessions. The invited talks will be followed by presentations that will couple to each other presenting a common theme. The ultimate goal of this symposium will be to capture the latest developments in the field of heterogeneous polymer materials research. It is hoped that given the strong interest from both the governmental, academic and industrial sectors, this symposium will be offered annually by MRS.
