Researchers develop graphene fibers for efficient heat management in electronics
Researchers have developed graphene fibers that combine carbon nanotube strength with copper-like thermal conductivity, promising advances in heat management for electronics and aerospace. This break…
In 2026, researchers announced a breakthrough in graphene fiber production that could revolutionise heat management in electronics and aerospace, following a 15‑year research path that began with a 2011 discovery of graphene oxide liquid crystals at Korea’s KAIST. The new fibers combine the strength of carbon nanotubes with a thermal conductivity that rivals copper, making them attractive for cooling high‑performance chips and for use in lightweight aircraft panels.
Graphene’s unique structure gives it exceptional heat‑conduction properties, but turning it into usable material has been difficult. The 2011 work showed that graphene oxide could be assembled into liquid crystals that align when stretched, allowing the creation of continuous fibers with minimal defects. Early applications of the technology appeared in antibacterial toothbrushes and smart sports
