Aerogel composite

Abstract

The present disclosure relates to an aerogel composite having excellent insulation even when exposed to a high-temperature environment. An aerogel composite comprising: a fiber substrate; and aerogel including one or more pores, wherein a surface resistance at room temperature (23±2° C.) of the aerogel composite is 1×1012 Ω/sq to 1×1016 Ω/sq; a surface resistance measured after heating the aerogel composite at a temperature of 200° C. for 1 hour is 1×1012 Ω/sq to 1×1016 Ω/sq; and the aerogel composite has R200, which is a real number of 0 to 4, in Equation 1 below: R200=log10{(Surface resistance of aerogel composite after heating at 200° C. for 1 hour)/(Surface resistance of aerogel composite before heating)}[Equation 1].
