Modification of a porous silicagel with the microporous carbon was studied for the purposes of controlling hydrophilic properties of the pore surface of silicagel and creating a novel porous material of dual uniform-pore structure. Silicagels of the mono-dispersed pore were impregnated in phenol resin dissolved into acetone, dried and heat-treated at 800°C for 1 hour to carbonize the resin onto the silica pore. The procedure was repeated up to seven times for the phenolic porous carbon to deposit cumulatively over the mesopore of the silicagel support. The adsorption capacities of steam, carbontetrachroride, TIPB (1, 3, 5-Triisopropylbenzene) and PFTBA (Perfluoro-tributylamine) were measured at 30°C. Effects of the microporous carbon deposit on the hydrophilic properties and molecular sieving properties were discussed.
