201. Abstract
Native cellulose samples with high crystallinity were pyrolyzed up to about 2000C and the resulting carbon structures were examined. The drying method for water-swollen or water-suspended cellulose prior to pyrolysis was found to significantly affect preservation of the large surface area of the original cellulose i.e., solvent exchange drying (water-ethanol-t-butyl alcohol) of hydrogels and rapid freeze drying of water suspended particles by spraying onto a cooled copper plate gave surface area of cellulose of 60-120 m 3/g, about twice of those by ordinary freeze-drying. The carbons derived from these materials had nearly the same surface area as the staring cellulose and maintained the nanofibrillar morphology.
