Recent advances in novel aerogels through the hybrid aggregation of inorganic nanomaterials and polymeric fibers for thermal insulation

Aerogel is a nanoporous solid material with ultrahigh porosity, ultralow density, and thermal conductivity, which considered to be one of the most promising high-performance insulation materials today. However, traditional pure inorganic aerogels (i.e., silica aerogel) exhibit inherent structural brittleness, making their processing handling difficult, manufacturing costs are relatively high, limits large-scale practical use. The recently developed aerogel based on polymer nanofibers has conductivity excellent elasticity, designable multifunction. More importantly, one-dimensional directly used as building blocks construct network via gelation-free process. This greatly simplifies preparation process, thereby bringing opportunities for applications. aggregation nanomaterials very attractive strategy obtaining highly flexible, easily available, multifunctional composite aerogels. Therefore, this review summarizes recent advances in novel through hybrid polymeric fibers insulation. main routes, porous microstructure, mechanical properties, properties applications these highlighted. In addition, various future challenges faced by discussed review.
