Molecular Relaxation Dynamics and Structure of Poly(ethyl- eneoxide) Complexes with Metal Ions in Solution

该奖项由材料化学和化学加工计划颁发，以支持犹他大学的E.Eyring博士、理工大学的S.Petrucci博士和布鲁克海文的T.Skotheim博士的合作研究。研究了碱金属和碱土金属阳离子与聚氧乙烯(PEO)络合的结构和动力学。这些聚醚络合物在轻型充电电池中既是重要的基础材料，也是固体电解质。通过射频和超高频超声弛豫谱、射频和微波介电弛豫谱、音频电导率、拉曼和红外振动谱、X射线光电子能谱和同步辐射研究聚醚络合物的动力学。系统地探讨了聚醚链长和配位阳离子性质的影响。

This award is made in the Materials Chemistry and Chemical Processing Program to support the collaborative research of Dr. E. Eyring at the University of Utah, Dr. S. Petrucci at Polytechnic University and T. Skotheim at Brookhaven. The research will deal with the structure and dynamics of alkali and alkaline earth cation complexation with polyethylene oxide(PEO). These polyether complexes are of interest both fundamentally and as solid electrolytes in light-weight rechargeable batteries. The dynamics of polyether complexes will be studied by means of Radiofrequency and UHF ultrasonic relaxation spectra, radiofrequency and microwave dielectric relaxation spectra, audiofrequency electrical conductivity, Raman and infrared vibrational spectra, and X-ray photoemission and synchrotron radiation studies. Effects of polyether chain length and the nature of the coordinating cation will be systematically explored.
