为有效调整和控制管式炭膜(TCM)内表面的孔结构,采用浸渍法对管式炭膜进行处理,并通过调整浸渍液浓度和改变浸渍处理的次数分析浸渍对膜内孔径分布的影响.扫描电子显微镜(SEM)观察得知:浸渍处理能够有效修复管式炭膜表面上的孔缺陷.同时,浸渍前后样品的孔径分布数据揭示出管式炭膜的微孔尺寸随着浸渍液浓度和浸渍次数的增加而变小,且孔分布也随之变窄.说明通过调整浸渍条件可以实现管式炭膜孔径和孔结构的有效控制.
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.
