Abstract: The present disclosure provides an aerogel formed of a tannin-containing porous material including a polymeric material, a tannin, and a clay. In some embodiments, the tannin-containing porous material is produced by forming an aerogel precursor including a polymeric material, a tannin, and a liquid dispersion medium; freezing the aerogel precursor; and freeze drying. In other embodiments, the tannin-containing porous material is produced by coating a formed porous aerogel material with a tannin-containing coating solution including tannin dispersed therein. The aerogel provides a flame retardant material having improved mechanical properties.
