项目摘要
TECHNICAL SUMMARY: Herein we propose the development of new synthetic strategies that will lead to a variety of new soft materials that should have unique properties. We plan to synthesize these new materials by combining the state-of-the-art in traditional polymer synthesis methodologies with recent breakthroughs in soft lithography that we have pioneered called Particle Replication in Non-wetting Templates (PRINT®). What we hope to try to achieve is the synthesis of mesoscopic variants of conventional polymers that we will call ?meso-polymers?. By ?meso-polymers? we mean molded polymeric objects that are filamentous in nature that have length to diameter ratios that rival that of synthetic polymers. This has never been achieved before. It will be very interesting to see if we can synthesize meso-polymers having various and tunable solubility parameters (varying degrees of hydrophilic, hydrophobic, fluorous phases); various degrees of stiffness (analogy to rod-coil polymers); controllable lengths (% compositions); and connectivity (ABA, ABC, ABABA, etc). If we can achieve such high aspect ratios, meso-polymers should provide great insight into how polymers entangle and form higher order structures. The proposed research effort has three aims involving the attempted i) synthesis of meso-polymers; ii) the characterization of the physical properties of single-phase meso-polymers; and iii) the synthesis and mesoscopic characterization of multi-phase meso-polymers.NON-TECHNICAL SUMMARY: Polymers are long chain molecules with very high length to diameter ratios that impact our everyday lives as plastics, coatings, adhesives, and rubbers. They are found in everything from acrylic paints and rubber tires to plastic bottles, bulletproof glass, and computer keyboards. The fabrication of polymers results in materials that have a distribution of lengths and, due to the fibrous nature of polymers, are entangled with one another. Making polymers out of more than one material is very complicated and introduces composition as another variable. To further the science and understanding of this important class of unique materials, we propose to fabricate precisely controlled polymer mimics that we term ?meso-polymers.? The meso-polymers will be fabricated using a molding technique called PRINT® that is akin to baking muffins in a muffin pan but on a much much smaller scale. Using PRINT, meso-polymers will be fabricated out of a variety of materials with very high aspect ratios approaching 10 million! The successful synthesis of these materials will have a significant impact on the polymer science community. It is expected that meso-polymers will have fundamentally different characteristics from conventional polymer molecules and it is anticipated that the success of this program will change the way people think about polymer molecules and indeed new physics will have to be invoked to understand the properties and characteristics of these materials. In addition to advancing the understanding of polymeric materials, this project will also promote teaching, training and entrepreneurship. Graduate students will learn how to solve problems by starting with polymer synthesis moving to material properties and applications. Anticipating that we will have a breakthrough with this program, several initial patent applications will inevitably be developed which will be done by the student co-workers on this project. Such patents will protect our ability to do translational science and engage the outside community to address heretofore unmet needs in numerous fields. The filing of these patents and the multi-disciplinary interactions will also provide great educational experiences for the students involved. Additionally, it is expected that the research results will be incorporated, where appropriate, into the teaching of undergraduate organic chemistry and of graduate polymer chemistry to help students appreciate the utility of basic concepts and the translational opportunities of innovation.
技术概要:在此,我们提出了新的合成策略的发展,这将导致各种新的软材料,应具有独特的性能。我们计划通过将传统聚合物合成方法的最新技术与我们开创的称为非润湿模板中的颗粒复制(PRINT®)的软光刻技术的最新突破相结合来合成这些新材料。 我们希望尝试实现的是常规聚合物的介观变体的合成,我们将称之为?介观聚合物? 是谁?介观聚合物我们指的是具有与合成聚合物相匹敌的长径比的丝状性质的模制聚合物物体。 这是前所未有的。 这将是非常有趣的,看看我们是否可以合成介孔聚合物具有各种和可调的溶解度参数(不同程度的亲水性,疏水性,氟相);各种程度的刚度(类似于棒-线圈聚合物);可控的长度(%组成);和连接性(阿坝,ABC,ABABA等)。 如果我们能达到如此高的长径比,介观聚合物应该提供对聚合物如何缠结和形成更高级结构的深入了解。该研究工作有三个目标,包括尝试i)介观聚合物的合成; ii)单相介观聚合物的物理性能表征; iii)多相介观聚合物的合成和介观表征。非技术性概述:聚合物是长链分子,具有非常高的长径比,影响我们的日常生活,如塑料,涂料,粘合剂和橡胶。 从丙烯酸涂料、橡胶轮胎到塑料瓶、防弹玻璃和电脑键盘,它们无处不在。 聚合物的制造导致具有长度分布的材料,并且由于聚合物的纤维性质,材料彼此缠结。 用一种以上的材料制造聚合物是非常复杂的,并引入了组成作为另一个变量。 为了进一步科学和理解这一类重要的独特材料,我们建议制造精确控制的聚合物模拟物,我们术语?介观聚合物 中间聚合物将使用称为PRINT®的成型技术制造,该技术类似于在松饼盘中烘焙松饼,但规模要小得多。使用PRINT,介观聚合物将由各种材料制成,具有接近1000万的高纵横比! 这些材料的成功合成将对聚合物科学界产生重大影响。 预计介观聚合物将具有与传统聚合物分子根本不同的特性,预计该计划的成功将改变人们对聚合物分子的看法,并且必须调用新的物理学来理解这些材料的特性和特性。除了促进对聚合物材料的理解外,该项目还将促进教学,培训和创业。研究生将学习如何解决问题,从聚合物合成开始转向材料性能和应用。预计我们将有一个突破性的这个程序,几个初步的专利申请将不可避免地开发这将是由学生的同事在这个项目上完成。 这些专利将保护我们进行转化科学的能力,并使外部社区参与解决许多领域迄今未满足的需求。 这些专利的申请和多学科的互动也将为相关学生提供很好的教育体验。 此外,预计研究结果将在适当的情况下纳入本科有机化学和研究生高分子化学的教学,以帮助学生欣赏基本概念的实用性和创新的转化机会。
