“…The incorporation of the graphene flakes hinders the diffusion of gases through the polymer matrix, by forming a “maze‐like” structure in the matrix . In the literature, FLG flakes are used in the polymer composites to decrease the gas permeation . In our study, the OP of the composites ABS‐FLG and ABS‐FLG‐PMMA with a loading of 0.1 wt.…”

One of the applications of graphene in whichi ts scalable production is of utmost importance is the development of polymer composites. Amongt he techniques used to produce graphene flakes,t he liquid-phase exfoliation (LPE) of graphite stands out due to its versatility and scalability.H owever,s olvents suitable for the LPE processa re generally toxic and have ah igh boilingp oint, making the processing challenging. The use of low boiling point solvents could be convenient for the processing, due to the easiness of their removal. In this study,the use of poly(methyl methacrylate) (PMMA) as as tabilizing agent is proposed for the production of graphene flakes in al ow boiling point solvent, that is, acetone. The graphene dispersions produced in the mixture acetone-PMMA have higherc oncentration, + 175 %, and contain ah igher percentageo ff ew-layer graphene flakes (< 5layers), that is, + 60 %, compared to the dispersions preparedi na cetone. The as-produced graphene dispersions are used to develop graphene/acrylonitrile-butadiene-styrene composites. The mechanical properties of the pristine polymer are improved, that is, + 22 %i nt he Young's modulus, by adding 0.01 wt. %o fg raphene flakes. Moreover, ad ecrease of % 20 %i nt he oxygen permeability is obtained by using 0.1wt. %o fg raphene flakes filler,c ompared to the unloaded matrix.[a] S.Supporting information and the ORCID identification number(s) for the author(s) of this articlecan be found under: https://doi.

In this study, DBNs‐aminated layered double hydroxide (ALDH) was prepared by connecting ALDH with hydroxylated boron nitride nanosheet (OH–BNs) which was obtained by high‐temperature steam method from hexagonal boron nitride nanosheet (h‐BNs) through the polydopamine. DBNs‐ALDH was characterized by fourier‐transform infrared spectroscopy, x‐ray diffraction, scanning electron microscope, energy dispersive spectrometer, transmission electron microscope, Raman, and x‐ray photoelectron spectroscopy analyses to prove the success of the synthesis. Change of chloride ion concentration was chosen to evaluate the ion exchange function of DBNs‐ALDH. Then, the epoxy resin (EP) mixed with DBNs‐ALDH was coated on the Q215 steel to form a composite epoxy coating. The electrochemical impedance spectroscopy test and brine immersion test were used to characterize the anticorrosion performance of composite EP coating. The results revealed that the DBNs‐ALDH reinforced the anticorrosion performance of the EP coating.
