Abstract: |
The surface free energies of high structure carbon black CD2117,CRX2125 and carbon black N330,N550 were investigated by using inverse gas chromatography method.The results showed that,the dispersion free energy of carbon black increased when the specific surface area of carbon black increased.The linear correlation coefficient of specific surface area and dispersion free energy was 0.839 32,indicating a good correlation.When the high structure carbon black was treated at different temperatures,the number of surface oxygenic groups of carbon black decreased,and the dispersion free energy increased.On the other side,when the carbon black was treated by oxidation,the number of surface oxygenic groups of carbon black increased,and the dispersion free energy decreased,which illustrated that the oxygenic groups were not the active centers of adsorbing rubber. |
