        Tunable electrorheological performance of silicone oil suspensions based on controllably reduced graphene oxide by surface initiated atom transfer radical polymerization of poly(glycidyl methacrylate)

        This article is focused on the controllable reduction of the graphene oxide (GO) particles as asimultaneous process during surface initiated atom transfer radical polymerization (SI-ATRP) providinghybrid particles with tailored conductivity and substantial polymer shell on the particles tunable by SIATRPconditions. The main advantage of such approach is that both the compatibility improvement, dueto the polymer layer, and conductivity tuning, due to partial GO reduction, were simply achieved insingle-step reaction providing electrorheological (ER) system with enhanced performance in comparisonto either neat GO or similar non-covalently bonded GO-polymer hybrids. The presence of the poly(glycidyl methacrylate) (PGMA) on the surface of GO was investigated using FTIR spectrometry,transmission electron microscopy and thermogravimetric analysis and their chain length (Mw) andpolydispersity index (PDI) were determined by 1H NMR and GPC, respectively. Two different GO-PGMAparticle systems varied in Mw and PDI and also in electrical conductivities were prepared and theirelectro-responsive capabilities were investigated. The reduction of GO particles was confirmed by Ramanshift as well as conductivity measurements. Electrorheological (ER) performance was investigated atvarious electricfield strengths and repeatability of the phenomenon was confirmed by 10 on/offfieldcycles. Finally, with the help of dielectric measurements of GO-PGMA based ER suspensions,fitted byHavriliak–Negami model, the relaxation processes were properly investigated and the results werecorrelated with those obtained from electrorheological measurements.
