Metallic Carbons via Polymer Thermalization

这项研究的目的是探索通过含氮聚合物的热分解在纤维或薄膜中形成改性石墨化结构的可能性。该计划将侧重于通过1500℃以上的热处理将多氰(PCN)转化为碳纤维，并对其机械、电、微结构和磁性进行表征。这些样品将被掺杂贵金属和过渡金属以及金属氯化物，以试图以受控的方式改变它们的磁性、电子和机械性能。所研究的石墨材料表现出高导电性、半导性和金属性。这种材料将有趣的电子性能与高热稳定性、良好的机械性能和加工性结合在一起。

The objective of the research is to investigate the possibility of creating modified graphitic structures in fibers or thin films via the thermal decomposition of nitrogen- containing polymers. The program will emphasize conversion of polycyanogen (PCN) to carbon fibers via thermal treatment above 1500 C., and characterization of the mechanical, electrical, microstructural, and magnetic properties. The specimens will be doped with noble and transition metals and metal chlorides in an attempt to alter their magnetic, electronic, and mechanical properties in a controlled manner. The graphite materials being investigated exhibit highly conducting, semiconducting, and metallic behavior. The materials combine interesting electronic properties with high thermal stability, good mechanical properties, and processability.
