以间甲酚为原料 ,与甲醛在NaOH催化作用下经溶胶—凝胶过程制备出新型块状纳米材料炭气凝胶 ,考察了原料配比对凝胶时间和气凝胶特性的影响 ,用TG、FT -IR、TEM和低温N2 吸附等手段表征了气凝胶的微结构。
A new type of bulk carbon nanomaterial carbon airgel was prepared by sol-gel process with m-cresol as the raw material and formaldehyde catalyzed by NaOH. The effects of the ratio of raw materials on the gelation time and the properties of the aerogels were investigated. , FT-IR, TEM and N2 adsorption at low temperature were used to characterize the microstructure of airgel.
