Metallic Carbons via Polymer Thermalization

该研究的目的是研究通过含氮聚合物的热分解在纤维或薄膜中产生改性石墨结构的可能性。该项目将强调通过1500℃以上的热处理将多氰（PCN）转化为碳纤维，并对其机械、电气、微观结构和磁性进行表征。样品将掺杂贵金属、过渡金属和金属氯化物，试图以可控的方式改变其磁性、电子和机械性能。所研究的石墨材料表现出高导电性、半导体性和金属性。该材料结合了有趣的电子性能、高热稳定性、良好的机械性能和可加工性。

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.
