Transition Metal Compatibilization of Immiscible Polymer Blends

这项研究的主要目标是开发通过过渡金属络合来增容不相容聚合物共混物的方法。当金属中心与两种不同聚合物中的配体配位时，就会发生混溶。这些聚合物/过渡金属配位络合物是独一无二的，因为它们的宏观物理性质不遵循简单的加和性规则，这是弱相互作用聚合物混合物的特征。由于反应性共混会在两条不同的链之间产生配位交联键或共价键，所以最终产品表现出不同寻常的热机械性能。这是超分子设计的延伸，代表了跨学科高分子科学和工程的一个新前沿。通过少量过渡金属络合物的转变将不相容的聚合物共混物转变为相容混合物的策略对于需要协同宏观物理性能的工业应用是非常有吸引力的。本研究中的方法代表了寻找强相互作用的功能聚合物、三元共混物和AMP；络合物的下一步。这项有机-无机杂化材料的研究将对纳米技术的最先进水平做出重大贡献，并在最终产品中提供异常新颖和有用的性能。

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.
