This article introduces a study on the fabrication of new composite materials by hybridizing conductive nanocarbon-coated glass fibers with polymers. The results show that the composite material has good electrical conductivity and thermal conductivity, making it suitable for applications such as electromagnetic shielding.
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 10(8) 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.
