High-performance polystyrene/graphene-based nanocomposites with excellent anti-corrosion properties

Development and Characterization of Anticorrosion and Antifriction Properties for High Performance Polyurethane/Graphene Composite Coatings

“…Gr has attracted considerable attention owing to its extraordinary electrical and physical properties, especially its impermeable nature [32][33][34]. There are a number of studies showing that adding Gr and its derivatives to a polymer coating can enhance the corrosion performance of the coating [19][20][21][22][23][24][25][26][27][28][29][30][31]. Yu et al [19] reported that the corrosion protection efficiency increased from 37.90% to 99.53% with the incorporation of 2 wt.% modified GO in the polystyrene polymer matrix.…”

Hayatgheib et al [23] ascertained that incorporation of GO-PANI nanosheets into the epoxy matrix significantly enhanced the barrier performance and ionic resistance of epoxy coating.…”

“…They showed that the incorporation of a small number of nanoparticles-especially Fe 2 O 3 and halloysite clay-into the epoxy coating can enhance the corrosion resistance of the epoxy-coated steel. In recent years, it was reported that carbon derivatives, such as carbon nanotubes (CNTs) [16][17][18], graphene (Gr) and graphene oxide (GO) [19][20][21][22][23][24][25][26][27][28][29][30][31] can be used as anti-corrosion additives to organic coatings. Gr has attracted considerable attention owing to its extraordinary electrical and physical properties, especially its impermeable nature [32][33][34].…”

The effect of varying carboxylic-group content in reduced graphene oxides on the anticorrosive properties of PMMA/reduced graphene oxide composites

“…In addition to the barrier effect, the higher carboxylic-group content of TRG-300 leads to the formation of stronger hydrogen bonds between the hydroxyl groups of TRG and the carbonyl groups of PMMA. Therefore, the PTC-33 coating could act as a very strong passivation layer against corrosion [24].…”

“…In addition, there have been studies into using thermal reduction at different temperatures to obtain FGSs of varying degrees of functionalization [22]; these FGSs were subsequently added into polymer matrices of composites and the resultant electrochemical properties were investigated [23]. Recently, some studies reported the anticorrosive capabilities of composites containing graphenebased materials such as GNSs and GO [24][25][26][27]; however, there have been no reports on the addition of FGSs with different degrees of functionalization to PMMA matrices of composites and the resultant impact on the anticorrosive properties. Therefore, in this study, we present the first comparison of the anticorrosive properties of PMMA/thermally reduced graphene oxide (TRG) composite (PTC) coatings featuring TRGs with varying carboxylic-group contents.…”
