Description
Summary:Polymer/clay aerogel composites fabricated using the freeze-drying method and water as solvent has drawn extensive attentions during the past decade. Such aerogels possess layered or network microstructures, low thermal conductivities, and good thermal stabilities; of special interest, they generally have very low flammability, which could be influenced by the composition and microstructure of the aerogel composites. The fire performance of the aerogels can be further improved with flame retardant modifications. Polymer/clay aerogel composites can also serve as effective flame retardant coatings. The mechanisms of the flame retardancy of polymer/clay aerogel composites are also discussed herein. The thorough survey of the current literatures offers useful information to realize potential of polymer/clay aerogels and help guidance to design novel high-performance polymer/clay aerogel composites.
