Influence of formamide/dimethylformamide on properties of silica aerogel

Wang Dongdong,Wang Gang,Wang Jiandong,Wang Zehua,Ding Shuqiang,Li Hongxia State Key Laboratory of Advanced Refractories,Sinosteel Luoyang Institute of Refractories Research Co.,Ltd.,Luoyang 471039,Henan,China  
Silica aerogel was prepared using industrial silica sol as silica source,formamide(FA) or N,N-dimethylformamide(DMF) as additive(the molar ratio of FA/DMF to silica is 0∶1,0.1∶1,0.25∶1,0.5∶1,0.75∶1 and 1∶1,respectively) via sol-gel method combined with carbon dioxide supercritical drying.Influence of FA/DMF on the gelation time,bulk density and specific surface area of silica aerogel was discussed.The results show that FA/DMF is favorable for perfect aerogel samples without cracking;because FA/DMF can delay the hydroxy polycondensation reaction and affinity interaction of ethanol,the increase of their addition can obviously prolong the gelation time but scarcely influence the bulk density and specific surface area of silica aerogel.The prepared silica aerogel possesses nano-porous structure with high specific surface area of 220-235 m2·g-1 and low density of 180-198 kg·m-3.
