Abstract Protection against high heat conditions is of utmost importance in different specific fields, such as firefighting. The clothing of a firefighter is the last line of defence for survival. Though over time firefighters’ protective clothing (FPC) has improved significantly, still today firefighters receive severe burn injuries on duty. Hence, researchers all over the world continue to investigate innovative materials, methods and practices to improve the performance of FPC. Aerogel is an extremely heat-insulating material. It has very good potential to be used in FPC.The aim of this study is to explore the application potential of aerogel on textiles for thermal protection in high heat conditions, especially in firefighting. For the first time, the current study shows how the heat-insulating property of aerogel can be coupled with the heat-absorbing capability of phase change material (PCM) in FPC. PCMs are well known for their use in thermoregulating clothing because they are capable of absorbing and releasing heat as necessary. Aerogel was applied on the first layer of protection while PCM acted as a supportive layer from next to the skin surface. The combination has the capability of shielding the body from high heat and absorbing metabolic heat. An easy-to-apply coating additive was prepared by housing PCM in aerogels’ nanopores and a bench-scale instrument was developed to evaluate the radiation heat protection of various layers of FPC at the same time in a multilayer construction. The flammability risk of PCM-containing thermal liners has also been investigated. Finally, the study shows an innovative application of existing aerogel nonwoven in FPC and develops alternative methods to produce nonwoven fabric containing aerogel through needleless electrospinning.
