Abstract
In this article, reduced graphene oxide/glass composite fiber was prepared from mixing graphene oxide and glass powder by ultrasonic dispersion, planetary grinding, high-temperature sintering, and melting wire drawing. The effects of reduced graphene oxide content on the mechanical and electrical properties of the fiber were investigated. Thermal gravimetric analyzer, differential scanning calorimeter, x-ray diffraction, and energy-dispersive x-ray spectroscopy analysis revealed that the graphene oxide was reduced to reduced graphene oxide in the sintering process and the performances of the composite fiber were improved. The tensile strength of reduced graphene oxide/glass composite fiber was 20% higher than the pristine glass fibers by the addition of 0.5 wt% of reduced graphene oxide. Reduced graphene oxide content was positively correlated with composites conductivity, and according to the percolation theory, the percolation threshold of reduced graphene oxide/glass composite fiber was about 0.5 wt%, and the conductivity of the composite fibers was increased by four orders of magnitude compared to the pristine glass fibers when the content of reduced graphene oxide was 0.5 wt%.
Highlights
Glass fibers (GFs) are widely used in aviation, aerospace, navigation, construction, and other industrial fields due to its high temperature resistance, corrosion resistance, high strength, and other advantages.[1,2,3,4,5] with the development of the new technology all over the world, many novel, light, and high-strength fibers such as carbon fiber and silicon carbide fiber have been proposed;[6,7] the performances of the traditional GFs are not able to meet the needs of high-tech fields anymore
We propose a strategy to synthesis reduced graphene oxide (RGO)/GF, which may improve the comprehensive properties of GF
It can be seen that compared with the smooth cylindrical surface of ordinary GFs, the addition of RGO increased the roughness of the surface of RGO/GF
Summary
Glass fibers (GFs) are widely used in aviation, aerospace, navigation, construction, and other industrial fields due to its high temperature resistance, corrosion resistance, high strength, and other advantages.[1,2,3,4,5] with the development of the new technology all over the world, many novel, light, and high-strength fibers such as carbon fiber and silicon carbide fiber have been proposed;[6,7] the performances of the traditional GFs are not able to meet the needs of high-tech fields anymore. It is urgent to explore new composite GF which has better comprehensive performance under the premise of inheriting the original excellent performance.[8].
