“…However, this process could cause undesired permanent structure changes of GO, and it may usually be conducted in organic solvents, which would not be environmental friendly . Sometimes, a simple non‐covalent functionalization method, which typically involves van der Waals forces, electrostatic interaction, hydrogen bond, etc., could be as effective as the covalent approach. For example, Liu et al .…”

Ionic liquid 1‐allyl‐3‐methyl‐imidazolium chloride (AMICl) is used to fine‐tune the surface properties of graphene oxide (GO) sheets for fabricating ionic liquid functionalized GO (GO‐IL)/styrene‐butadiene rubber (SBR) nanocomposites. The morphology and structure of GO‐IL are characterized using atomic force microscope, X‐ray diffraction, differential scanning calorimetry, X‐ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, UV‐vis spectra and Raman spectra. The interaction between GO and AMICl molecules as well as the effects of GO‐IL on the mechanical properties, thermal conductivity and solvent resistance of SBR are thoroughly studied. It is found that AMICl molecules can interact with GO via the combination of hydrogen bond and cation–π interaction. GO‐IL can be well‐dispersed in the SBR matrix, as confirmed by X‐ray diffraction and scanning electron microscope. Therefore, the SBR nanocomposites incorporating GO‐IL exhibit greatly enhanced performance. The tensile strength, tear strength, thermal conductivity and solvent resistance of GO‐IL/SBR nanocomposite with 5 parts per hundred rubber GO‐IL are increased by 505, 362, 34 and 31%, respectively, compared with neat SBR. This method provides a new insight into the fabrication of multifunctional GO‐based rubber composites. Copyright © 2016 John Wiley & Sons, Ltd.

“…The pattern of GO shows a typical (001) diffraction peak at approximately 10.3 , corresponding to a dspacing of 0.86 nm. 37 Compared with GO, the D and G bands of RGO are red shied to 1330 cm À1 and 1564 cm À1 , respectively, possibly because of the restored conjugated structure of graphene. For RGO, the characteristic peak of GO is absent, and a broad diffraction peak appears at approximately 25.8 (d-spacing of 0.35 nm), which is similar to the typical diffraction peak of graphite.…”

Reduced graphene oxide (RGO) was prepared by the reduction of graphene oxide (GO) with rhodanine.During the reduction, rhodanine was converted into polyrhodanine via oxidative polymerization initiated by GO, and the RGO was subsequently decorated with polyrhodanine. The reduction process and polymerization have been verified. Rhodanine reduced GO with high efficiency. Additionally, rhodanine is polymerized during the GO reduction process. The wrapping of polyrhodanine onto RGO is also verified.Using this novel modification process, the elastomer/graphene composites were prepared by the in situ interfacial modification of elastomer/GO compounds with rhodanine during the processing. Because of the unique reactivity of polyrhodanine during curing, strong interfaces were observed to form in the resulting elastomer/RGO composites. Furthermore, because of the substantially improved interfacial adhesion, combined with the improved dispersion state, the elastomer/RGO composites exhibited significantly improved mechanical properties compared with the elastomer/GO composites. Regarding the facile process and strikingly high modification efficiency, the present work offers new insight into designing high-performance elastomer/graphene composites by combining interfacial chemistry and curing chemistry. ; Fax: +86 20 22236688; Tel: +86 20 87113374 † Electronic supplementary information (ESI) available: Photographs of rhodanine and polyrhodanine dispersions, tensile modulus of SBR/GO and SBR/RGO composites, tan d curves of SBR/GO and SBR/RGO composites, vulcanization curves and curing data; schemes of potential accelerating mechanism, crosslink density for SBR/rhodanine compounds.

“…As summarized in Fig. 8, in comparison with the rubber composites with comparable tensile strength [10,[32][33][34][35][36][37][38][39][40], SBR/BM/TA composites exhibit a lower tensile modulus but a higher elongation at break, thus appearing more flexible without sacrificing the tensile strength. Such distinctive flexibility of SBR/BM/TA composites may be associated with interlayer sliding and separation loads, which has been applied to nano-flake filled composites [41].…”
