Aligned carbon film with novel structure was synthesized from Hongyuan washed coal by microwave plasma.Field-emission scanning electron microscopy (FE-SEM)
high resolution transmission electron microscopy (HRTEM) and energy dispersive X-ray spectroscopy (EDS) were used to characterize the microstructure of the products.The results indicated that the products were formed in the shape of aligned bamboo shoots
their out-layers possessed a higher degree of graphitization
the maximum width was about 170 nm and the length was 4—5 μm.The novel aligned carbon film is expected to have a great applied potential of field emission and intensifier of composite materials.
