To adjust and control the porous structure in the inner face of a tubular carbon membrane (TCM), impregnation methods were used, and the effects of impregnation on the pore size distribution were analyzed by adjusting impregnant concentrations and impregnation times. SEM images show that the impregnation treatment can repair the pore defects on the TCM surface. Data on the micropore size distribution indicate that the pore size of the TCM becomes smaller and its distribution becomes narrower with increasing impregnant concentrations and impregnation times, which indicates that impregnation conditions can be used to adjust the pore size and structure of the TCM.
