Elaboration of properties of graphene oxide reinforced epoxy nanocomposites

Abstract

In this research work, properties of graphene oxide (GO) based epoxy nanocomposites, prepared via the solution blending method, are elaborated. Different loadings (0.1-0.5 wt%) of GO were added into epoxy resin, and their effects were studied on their surface reaction, morphology, mechanical and thermal properties. It was found that a chemical modification, layer expansion and dispersion of filler within the epoxy matrix resulted in an improved interface bonding between the GO and epoxy matrix. The optimum amount of graphene nanostructures can be useful to improve the properties of epoxy nanocomposites for applications in adhesives to automotive.

Influence of Reduced Graphene Oxide on Epoxy/Carbon Fiber‐Reinforced Hybrid Composite: Flexural and Shear Properties under Varying Temperature Conditions

“…Four sets of samples (with/out) rGO were manufactured for flexural and shear testing using resin infusion technique. The 0.1, 0.2, and 0.3 wt% rGO was dispersed in epoxy resin using sonication process in parallel program as in our previous studies . This was achieved by sonicating the rGO powder in acetone for a 30 min before this acetone/rGO solution was then mechanically mixed into the epoxy resin for a further 30 min.…”

A review on the mechanical, electrical and EMI shielding properties of carbon nanotubes and graphene reinforced polycarbonate nanocomposites

“…Graphene has incredible properties as the lightest and strongest nanomaterial, compared with its ability to conduct heat and electricity better than other nanomaterials. Because of their excellent properties, it can be included into a large number of applications . Graphene has low mass density as compared with the classical fillers and also have high electrical and thermal conductivity, due to the sp 2 hybridized carbon atoms in the monolayer graphenes (Figure ).…”

Graphene oxide‐wrapped polyaniline nanorods for supercapacitor applications

“…They are classified in two different types depending upon the energy storage mechanism viz; electrical double layer capacitor (EDLC), based on electrostatic charges accumulated at the electrode-electrolyte interface and pseudocapacitors, based on Faradic charge reactions or redox reactions of the electroactive species on the surface of the electrode [1][2][3][5][6][7][8][9]. Recently, graphene oxide (GO) has been widely used in supercapacitor [1][2][3][7][8][9], drug delivery [10], gas sensing, photocatalysis [11], hybrid composites [12], and so on due to its promising electronic, thermal and mechanical properties along with high specific surface area and ease of aqueous processability obtained by the presence of oxide functional groups such as epoxide, carbonyl and carboxyl as defects [13][14][15]. GO can be prepared from the oxidation of graphite by different oxidizing agents such as potassium chlorate, fuming nitric acid, concentrated sulfuric acid, sodium nitrate, potassium permanganate, and so on by various methods [16].…”
