Abstract
Two multi-layer graphene (MLG)filmswere prepared on copper foils by flame synthesis technique with propane gas as carbon source at different temperatures( 6000 C and 7000 C).The structural, morphological and chemical properties, of the synthesized MLG were studied. X-ray diffraction shows that the structure of MLG films is polycrystalline with preferential orientation in the [101] direction. Morphological properties were observed by AFM images, the grain size and average surface roughness of the obtained MLG films are found to increasing with temperature increases and decreasing with the distance.The Fourier transform infrared spectroscopy (FTIR) spectrum showed the stretching vibration of C=C aromatic ring and the stretching vibration from C-C bond. Also the oxygen-containing functional groups have been appeared like C=O, C-O and C-OH.
