摘要提案标题：研讨会CC：非均相聚合物材料的输运行为编号：CBET-0646260首席研究员：Robert H Pachavis，机构：材料研究学会摘要：非均相聚合物材料和复合材料的输运行为研讨会将讨论NSF化学输运系统部门特别感兴趣的各种材料问题。研讨会的智力价值在于，因为它集中在特定的主题上，研讨会的个别会议将共同提供传输行为（电，热，质量），独特微结构的影响，基于聚合物基质中纳米级包裹体的复合材料的新表征和制造技术的协同图像。例如，以导电聚合物复合材料为重点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电磁干扰屏蔽、传感器和/或静电耗散层时，这些信息将是有价值的。其他会议的重点是聚合物复合材料中的热传输，将提供有用的信息，以创造具有改善导热性的特殊涂层，以更快地冷却热表面或为电子产品制造更有效的散热器。围绕质量传输的会议将讨论包装应用中的气体屏障、异质燃料电池膜和新型气液分离膜。例如，最近人们意识到混合基质膜中的界面现象对膜的性能起着关键作用。毫无疑问，这些效应在其他异质系统中也很重要。除了以实验研究为重点的会议外，研讨会还将包括旨在模拟运输现象的会议。例如，最近的原子模拟为碳纳米管中的输运提供了独特的见解，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，刚刚描述的每个领域的顶尖研究人员将应邀发表演讲，作为每个会议的主持人。受邀的演讲之后将会有演讲，这些演讲将会结合在一起，呈现一个共同的主题。本次研讨会的最终目标是捕捉多相高分子材料研究领域的最新发展。鉴于政府、学术界和工业界的强烈兴趣，希望MRS每年举办一次研讨会。

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.
