Abstract
The effect of ultrasonic irradiation for the polymerization of furfuryl alcohol (FA) with a pore-forming agent on the microstructure of the carbons derived from the furan resin was investigated. Tetra ethylene glycol (TEG) and ethylene glycol (EG) were examined as the pore-forming agents. In the system of FA-TEG, atendency for the surface area to increase with increasing power of ultrasonic wave was recognized. The irradiation under 400 W and 500 W gave the surface areas larger than 900 m2/g. The micropore volume and the surface area were the larges in the carbon derived from the furan resin made from the mixture with equivalent amounts of FA and TEG.
A comparison of the numbers of ethyl group between TEG and EG showed that the morphology and the microstructure were significantly different. The effect of TEG in terms of pore development was confirmed to bemore effective than EG.
