Graphitization index
WebAbout graphitization. Graphitization is a heat treatment process of carbon materials at high temperatures to form graphite structure. By graphitization, electrical conductivity, … WebThe intensity ratio of D and G peaks (I D /I G) is the index of defect density present in CNTs. At defect sites along the sidewalls and tube ends, graphitization probably takes place, and they can easily oxidize in order to generate open tubes. Open ends of CNTs generate a semi coherent interface with CTP crystals.
