This award is for the renewal of research previously supported under a Materials Research Group grant (DMR 8703399) at the University of California - Santa Barbara. The research of the group focuses on the design and synthesis on the supermolecular length scale of multi-functional, high performance electronic and optical polymer blends using gel processing. The morphology of these gels is being determined using x-ray diffraction, optical, scanning, and electron microscopy, mechanical, and electrical measurements, optical spectroscopy, luminescence, and photo-induced absorption. Polymers being investigated include ultra-high molecular weight polyethylene, polyvinyl alcohol, polyacrylonitrile, unblended conjugated polymer systems, and phase-segregated highly oriented polymer blends such as polyaniline/poly(p-phenylene terephthalamide). Materials are being processed into fibers, thin films, and conducting foams taking care to control the morphology, phase stability, and spinodal decomposition. The research is multi-disciplinary, combining condensed matter physics, synthetic chemistry, theory, and polymer science. This grant provides the ideal mechanism to train students to synthesize, process and characterize polymers, with the interaction of all of the scientific approaches and methods used to study polymers.

该奖项是对以前加州大学圣巴巴拉分校材料研究小组(DMR 8703399)资助的研究的续展。该小组的研究重点是利用凝胶工艺设计和合成多功能、高性能电子和光学聚合物共混物的超分子长度尺度。这些凝胶的形态通过X射线衍射、光学、扫描和电子显微镜、机械和电学测量、光学光谱、发光和光诱导吸收来确定。正在研究的聚合物包括超高相对分子质量的聚乙烯、聚乙烯醇、聚丙烯腈、未共混的共轭聚合物体系，以及相分离的高取向聚合物共混物，如聚苯胺/聚对苯二甲酸乙二酯。材料被加工成纤维、薄膜和导电泡沫，注意控制形态、相稳定性和调幅分解。这项研究是多学科的，结合了凝聚态物理、合成化学、理论和聚合物科学。这项资助提供了理想的机制，培训学生合成、加工和表征聚合物，并将所有用于研究聚合物的科学途径和方法相互作用。
