CNF (Carbon Nanofiber) is a ceramic-class nanomaterial composed of elongated carbon structures, typically produced through chemical vapor deposition or similar synthesis methods. CNFs are used in advanced composite reinforcement, thermal management systems, and electromagnetic shielding applications where their high aspect ratio and electrical conductivity provide significant performance advantages over conventional fillers. The material is particularly valued in aerospace, automotive, and electronics industries for lightweight structural composites and functional coatings, though it remains primarily in industrial and research-driven applications rather than commodity markets.
