Microstructure of Pyrolytic Carbon from Coal Tar Pitch Modified by Phenolic Resin

摘要

Coal tar pitch (CTP) was modified with phenolic resin (PF). The parent CTP and modified CTP were carbonized at different temperatures, then the products were characterized by scanning electron microscope(SEM) and X-ray diffraction(XRD). The results show that pyrolytic carbon of the parent CTP had formed lamella and banded structure. Modified CTPs' lamella and banded structures were easier to be formed. Also, high temperature is good for the graphitization of CTP, but it is not advantageous to form the lamella structure.
