Speaker Travel Support for "Polymers and Liquid Crystals" ACS Symposium; Boston, MA; August 19-23,2007

该提案要求NSF提供3000美元，用于在2007年秋季在马萨诸塞州波士顿举行的ACS全国会议（1923年8月，2007年）上举行的题为“聚合物和液晶”的POLY部门研讨会的演讲者差旅补助。本次研讨会的共同组织者是PI（CU博尔德）和教授C。来自爱荷华州大学的艾伦·盖蒙。本次研讨会的重点是展示在含液晶（LC）和基于LC的聚合物系统领域的新研究和应用方向。这种材料是重要的，因为LC提供了容易控制聚合物材料中的有序性和各向异性的能力，从而放大或改变特定的性质。此外，LC组分提供了在纳米尺度上控制聚合物结构的能力，以产生具有增强的化学和/或物理性质的有机纳米材料。纳米技术是学术界和工业界对许多学科都非常感兴趣的领域，目前也是国家科学和技术倡议。上一次关于聚合物和液晶的ACS POLY研讨会是在8年前的1999年秋季举行的。ACS还于2003年秋季在聚合物材料：科学与工程（PMSE）部门举办了一个非常小的研讨会，题为“纳米结构液晶/聚合物材料应用和设备”。从那时起，在LC聚合物系统中出现了许多新的研究方向。这些包括使用新的LC相和聚合物结构的新型材料;将新的功能特性集成到LC聚合物材料中;以及新的应用领域，包括功能涂层，膜，催化剂，组织工程支架和微致动器。本次研讨会将突出这些新的进展和研究方向，在这个令人兴奋的领域的聚合物化学和材料科学。鉴于高分子化学和纳米科学是NSF两个重要的研究和教育领域，我们相信这次研讨会将是NSF会议支持的理想候选人。在知识价值方面，这次研讨会将提供一个跨学科的论坛，介绍和讨论新的和以前未发表的结果，关于如何聚合物化学和液晶科学可以用于实现功能，有序的聚合物材料与相关的和有趣的性能。水的污染物聚合物化学与LC技术的结合已经产生了许多高性能有序聚合物材料（例如，用于高强度和防弹的主链LC聚（芳族聚酰胺）纤维），以及新的显示和光学技术（例如，聚合物分散LC（PDLC）显示器）。然而，聚合物和液晶领域仍处于非常早期的发展阶段。只有少数几类LC（主要是热致LC相）和聚合物结构（线性，侧链，交联树脂）已被组合和探索。LC和聚合物化学的新组合有望产生具有前所未有的结构和性能的新型有序聚合物材料。因此，研究人员必须了解新型LC聚合物材料的基本行为和结构，并看到它们在结构材料和光学材料之外的新应用领域中的潜力。本次研讨会将作为一种工具，帮助ACS的成员在聚合物科学和液晶技术的交叉研究的前沿。在更广泛的影响方面，本次研讨会将是一个方便，高调的场所，介绍学术和工业研究在液晶聚合物材料化学领域。与本次研讨会相关的讲座，海报和预印本将不仅用于教育ACS成员，而且还用于教育一般科学公众关于基于LC的有序聚合物系统的相关性。开始研究人员，研究生和博士后研究员）参与并了解聚合物化学和LC材料交叉点的令人兴奋的机会。

This proposal requests $3000 from the NSF for speaker travel assistance for a POLY Division symposium titled "Polymers and Liquid Crystals", to be held at the Fall 2007 ACS National Meeting in Boston, MA (Aug. 1923, 2007). The co-organizers of this symposium are the PI (CU Boulder) and Prof. C. Allan Guymon from the University of Iowa. The focus of this symposium is to showcase new research and application directions in the area of liquid crystal (LC)-containing and LC-based polymer systems. Such materials are important because LCs provide the ability to readily control order and anisotropy in polymer materials, and thereby amplify or modify specific properties. In addition, LC components offer the ability to control polymer architecture on the nanometer scale to generate organic nanomaterials with enhanced chemical and/or physical properties. Nanotechnology is an area of great interest to both academia and industry across many disciplines, and it is also currently a national science and technology initiative. The last major ACS POLY symposium on polymers and LCs was held 8 years ago in Fall 1999. The ACS also held a very small symposium in the Polymeric Materials: Science and Engineering (PMSE) Division entitled "Nanostructured Liquid Crystal/Polymeric Materials Applications and Devices" in Fall 2003. Since that time, a number of new research directions in LC polymer systems have emerged. These include new types of materials using new LC phases and polymer architectures; integration of new functional properties into LC polymer materials; and new areas of application, including functional coatings, membranes, catalysts, tissue engineering scaffolds, and micro-actuators. This symposium will highlight these new advances and research directions in this exciting area of polymer chemistry and materials science. Given that polymer chemistry and nanoscience are two important research and education areas within NSF, we believe this symposium would be an ideal candidate for NSF conference support.In terms of intellectual merit, this symposium will provide an interdisciplinary forum for the presentation and discussion of new and previously unpublished results on how polymer chemistry and LC science can be used to achieve functional, ordered polymer materials with relevant and interesting properties. taminants from water. The combination of polymer chemistry with LC technology has already lead to many high-performance ordered polymer materials (e.g., main-chain LC poly(aramid) fibers for high strength and ballistic protection), as well as new display and optical technologies (e.g., polymer-dispersed LC (PDLC) displays). However, the area of polymers and LCs is still at a very early stage of development. Only a handful of classes of LCs (mainly thermotropic LC phases) and polymer architectures (linear, side-chain, cross-linked resins) have been combined and explored. New combinations of LCs and polymer chemistries hold the promise of leading to new types of ordered polymer materials with unprecedented structures and properties. Consequently, it is important for researchers to understand the fundamental behavior and structure of new LC polymer materials, and also see their potential to be used in new application areas beyond structural materials and optical materials. This symposium will act as a vehicle to help keep members of ACS at the forefront of research at the intersection of polymer science and LC technology.In terms of broader impact, this symposium will be a convenient, high profile venue for the presentation of academic and industrial research in the area of LC polymer materials chemistry. The talks, posters, and preprints associated with this symposium will be used to educate not only ACS members but also the general scientific public on the relevance of ordered polymer systems based on LCs This symposium will also serve as an important platform for allowing young scientists (i.e., beginning investigators, graduate students, and postdoctoral fellows) to participate and learn about the exciting opportunities at the intersection of polymer chemistry and LC materials.
