A review on multifunctional aerogel fibers: processing, fabrication, functionalization, and applications

Novel, flexible, and transparent thin film polyimide aerogels with enhanced thermal insulation and high service temperature

“…Although silica aerogels have excellent thermal insulation performances with reported thermal conductivities even lower than air, they typically suffer from low mechanical performance and brittleness, which hinders their use in practical applications. 12,13 Organic-based aerogels, such as polyimide (PI), [14][15][16][17][18] polyamide, 19,20 and polyurethane (PU), 21,22 can be promising alternatives, as they exhibit more ductility and flexibility. In this context, PI aerogels with the thermal stability of up to 400 1C 14,23,24 are the only promising candidate for high service temperature.…”

Characterization of Phase Change Materials Fabricated with Cross-Linked Graphene Aerogels

“…To develop a porous supporting material for practical applications, synthesizing a foam structure is needed to match working materials [ 5 , 6 ]. In comparison to a typical foam, the 3D aerogel shows relatively low density, i.e., lots of pores in the internal structure [ 7 , 8 ]. The graphene aerogel is appropriate for fabricating polymer composite due to its high chemical stability and mechanical property [ 9 , 10 ].…”

In Situ Loading of Polypyrrole onto Aramid Nanofiber and Carbon Nanotube Aerogel Fibers as Physiology and Motion Sensors

“…With the advent of the Web and the Internet of Things, intelligent wearable electronic products have been increasingly developed for health monitoring, pedometers, and human–computer interactions. − Printed circuit boards made of glass fiber and resin can no longer meet the needs of flexible devices. The improved flexible devices using polyester and polyamines are mostly used in the fields of foldable displays, but few are directly used in human–computer interaction. , Nanocomposite conductive fiber is a new type of fibrous material that meets the requirements of flexible wearable devices; specifically, it is lightweight with high flexibility and strong weavability. , The matrix material of nanocomposite conductive fiber is mainly an organic polymer, such as poly­(methyl methacrylate), polyethylene terephthalate (PET), cellulose, and aramid nanofibers (ANFs). , As a one-dimensional nanomaterial, aramid nanofibers have obvious advantages in mechanical properties and weather resistance. , …”

“…8,9 As a one-dimensional nanomaterial, aramid nanofibers have obvious advantages in mechanical properties and weather resistance. 10,11 Aramid nanofibers inherit the high strength, acid and alkali resistance, and temperature resistance of poly(p-phenylene terephthalamide). They are further advantaged by a large specific surface area, numerous active sites, and good water dispersion.…”
