From: Poly(vinyl alcohol) freeze casts with nano-additives as potential thermal insulators
Results of the fire behavior tests of the freeze casts. (a) Sample 10-0 burns off completely. (b) The sample 10–0.5 MFC also burns off completely. (c) Sample 10-10-SiO2 after about one minute flame exposure. (d) Sample 10–5 NC after one minute of flame exposure.
