Abstract:

To further improve the comprehensive performance of thermal protective clothing and meet the needs of increasing thermal protection with reduced heat storage, a type of graphene aerogel material with low density, low thermal conductivity and good heat insulating property was prepared by the modified Hummers method, and a composite flame retardant fabric system was constructed. The thermal protective performance of graphene aerogel with different thickness was measured in a low radiation condition. The results show that the flame retardant composite fabrics with graphene aerogel block provides better thermal protective performance, with the time required to cause skin damage extending about 203% and the time required to generate skin burn extending about 218%. It is found that the relationship between the thermal protective performance and the graphene aerogel thickness is not linear. The water vapor transfer of the flame retardant composite fabrics with graphene aerogel block is around 10.4 g/(m2·24 h), presenting no significant difference compared to fabrics untreated by graphene aerogel.

Key words: graphene aerogel, flame retardant fabric, thermal protective performance, air layer, modified Hummers method
