采用低温氮吸附法研究了多孔粘土复合材料的孔径分布和孔结构,讨论了不同交联物对材料孔结构和孔径分布的影响,结果表明,材料合成条件特别是交联物的水解过程对多孔粘土的孔结构和孔径分布有十分重要的影响.
This paper investigated the pore structure and pore size distributions of some porous clay composites by using N2 adsorption at low temperature(77K) and discussed the influences of different crosslinking agents on its pore structure and pore size distribution. The results show that the synthesis conditions of porous clays, especially, the hydrolysed process of crosslinking agents, play a very important role in the influences in pore structure and pore size distributions of porous clays.
