Structural, electrical, and electromagnetic shielding properties of nanocarbon‐coated glass fiber‐reinforced polypropylene

Glass fiber-reinforced composites (GFRC), widely applied in the automobile, aerospace, domestic appliance, sport equipment, and other fields, are indispensable in modern society. In this article, conductive nanocarbon-coated glass fibers (NCGFs) were hybridized with suitable polymers for the fabrication of new composite materials. NCGFs have good dispersion and interfacial interactions within polypropylene matrices. The electrical conductivity of a nanocarbon-coated glass fibers-reinforced composite (NCGFRC) was increased 108 times more than that of a pure polymer, which provided the NCGFRC with an electromagnetic shielding efficiency (8.2–12.4 GHz) of 22 dB. At the same time, the thermal conductivity of NCGFRC was also improved. NCGFRC will expand the types of GFRC available and further expand the application of GFRC into other fields.
