Micro-structural analysis on carbon micro-coil

Based on the analysis oftransmlsslonelectronmlcroscopy(TEM),hlghresolutlonTEM (HRTEM),Raman soectrosconv and X-ray dlffractlon(XRD),the mlcrostructure of carbon mier。coils was exPlored、A nan。graPhltlc structure cetl(NGSC)was found to be the unit of carbon mier。oils with Inclusion of amorphous carbon and mutl一shell fullerenes between the NGSC And the carbon micro—coil has a dsordered structure In a macroscoplc scale -Fhe geometrical parameters of the caF- bon micro—coil were proposed.It wasfound that the chlral angle ofmlcro--colls prepared by dlfkrent research were similar,athough they had dfFerent dameters and coil pitch.Combining the mlcrostruc- ture anayses and geometrical characterlzatlon,a possble growth process of cartion micro--coils was dscussed
