โฆ Synopsis
X-ray photoelectron spectroscopy analysis shows that polyimide is thermally converted to glassy carbon during pyrolysis. Scanning tunneling microscopy gives direct evidence of the existence of small graphitic domains in the amorphous carbon matrix, and we believe that those surface graphitic structures may play a major role in the biocompatibility of carbon surfaces.

Insulator-to-metal transition of polyimide films can be performed by pyrolysis at high temperature as proposed by the authors. The maximum conductivity of the polyimide pyrolyzed at 950ยฐC for 0.5 h in a nitrogen atmosphere was measured to be 248 S/cm. The structure, electrical, and magnetic properti
