U.S.-France Cooperative Research: Synthesis, Pyrolysis and Detailed Characterization of Silicon Containing Preceramic Polymers

这一为期三年的奖项支持密歇根大学的理查德·M·莱恩和法国巴黎皮埃尔和玛丽·居里大学的雅克·利瓦奇在材料科学方面的美法合作研究。研究人员建议探索使用新型硅酸盐和硅酸铝作为氧化物和氮氧化物玻璃和陶瓷的聚合物前驱体。密歇根大学的实验室将合成一系列相关的含硅前驱体，根据加热时间表矩阵对它们进行热解。巴黎集团将通过Magic Angel Spin和固态核磁共振技术表征产品的化学成分、陶瓷相和微结构组成。这位美国研究人员将前体聚合物合成方面的专业知识带到了这次合作中。这与法国研究人员在溶胶-凝胶和陶瓷分析方面的成熟计划相辅相成。这项研究将促进对多组分(金属)氧化物/氮氧化物玻璃和陶瓷前驱体设计的基本原理的理解。

This three-year award supports U.S.-France cooperative research in materials science between Richard M. Laine of the University of Michigan and Jacques Livage of the Pierre and Marie Curie University, Paris, France. The investigators propose to explore the use of novel silicate and alumino silicate as polymer precursors to oxide and oxynitride glasses and ceramics. The University of Michigan laboratory will synthesize a series of related silicon containing precursors, pyrolize them according to a matrix of heating schedules. The Paris group will characterize the products' chemical composition, ceramic phase and microstructural makeup through Magic Angel Spinning and solid state NMR techniques. The U.S. investigator brings to this collaboration expertise in precursor polymer synthesis. This is complemented by the French investigator's well-established program in sol-gel and ceramics analysis. The research will advance understanding of the fundamental principles for design of precursors to multi- component (metallic) oxide/oxynitride glasses and ceramics.
