The goal of this research is to develop polymeric precursors for TiN and related transition metal nitride ceramic fibers. This work will involve a detailed exploration of the synthesis and chemistry of titanium-imido polymers (Ti(NR)2)x prepared by the reaction of Ti(NR'2)4 reagents with primary amines. Preliminary experiments indicate that these polymers can be drawn into fibers and the fibers then converted into TiN ceramic fibers. The in- depth characterization of the polymer to ceramic conversion will constitute an important part of the proposed research as will the materials characterization of the TiN ceramics which result from the polymeric precursors. Extensions of the research to developing polymeric precursors for other transition metal and rare earth nitrides and phosphides is also planned.

本研究的目标是开发 TiN 和相关过渡金属氮化物陶瓷纤维的聚合物前体。 这项工作将详细探索通过 Ti(NR'2)4 试剂与伯胺反应制备的钛亚氨基聚合物 (Ti(NR)2)x 的合成和化学。 初步实验表明，这些聚合物可以拉制成纤维，然后将纤维转化为TiN陶瓷纤维。 聚合物向陶瓷转化的深入表征将构成拟议研究的重要组成部分，由聚合物前体产生的 TiN 陶瓷的材料表征也是如此。 还计划将研究扩展到其他过渡金属和稀土氮化物和磷化物的聚合物前体的开发。
