项目摘要

9902657BelfioreThe primary objective of this research is to develop methodologies for compativilizing immiscible polymer blends via transition metal complexation. Miscibility occurs when the metal center coordinates to ligands in two different polymers. These polymeric/transition-metal coordination complexes are unique because their macroscopic physical properties do not follow the simple rule of additivity that is characteristic of weakly interacting polymer blends. The final products exhibit unusual thermo-mechanical properties because reactive blending generates a coordination crosslink or a covalent linkage between two dissimilar chains. This is an extension of supramolecular design that represents a new frontier in interdisciplinary macromolecular science and engineering. Strategies to transform immiscible polymer blends into compatible mixtures via small amounts of a transitions of a transition-metal complex are extremely attractive for industrial applications where synergistic macroscopic physical properties are desired.The methodologies under investigation in this study represent the "next step" in the search for strongly interacting functional polymers, ternary blends & complexes. This research on organic-inorganic hybrid materials will contribute significantly to the state-of-the-art in nanotechnology, and offer unusually new & useful properties in the final products.

本研究的主要目的是开发通过过渡金属络合使不混溶聚合物共混物相容的方法。当金属中心与两种不同聚合物中的配体配位时，发生混溶性。这些聚合物/过渡金属配位络合物是独特的，因为它们的宏观物理性质不遵循弱相互作用聚合物共混物的特征的简单的加和性规则。最终产品表现出不寻常的热机械性能，因为反应性共混在两个不同链之间产生配位交联或共价键。这是超分子设计的延伸，代表了跨学科大分子科学和工程的新前沿。通过少量的过渡金属配合物的过渡将不混溶的聚合物共混物转化为相容的混合物的策略对于其中协同宏观物理性质是desirable.The方法的工业应用是非常有吸引力的，在这项研究中的调查代表的“下一步”在寻找强相互作用的功能聚合物，三元共混物配合物。这项关于有机-无机杂化材料的研究将对纳米技术的发展做出重大贡献，并在最终产品中提供不同寻常的新的有用特性。
