The extensively used latex mixing approach to prepare graphene can improve the graphene dispersion but meets some challenges in the preparation of high content carbon black filled rubber system like a rubber tire. Owing to the high melt viscosity of the rubber/graphene masterbatch, the dispersion of carbon black is not perfect during twin-roll mixing and some aggregates will be formed. Here we proposed a wet compounding process, combined with ultrasonically assisted latex mixing, named as the WCL method to prepare reduced graphene oxide/carbon black/natural rubber (rGO/CB/NR) composites. The morphological observations confirmed that both graphene and carbon black can be evenly dispersed in the rubber composites. The incorporation of rGO also improves the hardness, thermal conductivity and anti-aging properties of the composites. The rGO/CB/NR composites prepared by the WCL method possess better mechanical properties compared to conventional latex mixing. The entanglement-bound rubber tube model was utilised to understand the reinforcing mechanism.  相似文献

Industry is constantly demanding for materials with differential properties that explores nanoscale fillers functionality. Unfortunately, most of the papers present processing methods that are hard to scale up. Effects in addition different amounts of multiwall carbon nanotubes (MWCNT) and few-layer graphene (FLG) on cure behaviour, viscoelastic, mechanical and electrical properties of a hydrogenated nitrile butadiene rubber (HNBR) are investigated and compared with those composites having carbon black (CB) as filler. Looking for scale up the produced nanocomposites, rubber composites were produced in a closed mixing chamber by melt mixing with unmodified fillers. Addition of nanotubes reduces curing time. Microstructural analyses indicate that FLG cannot be easily dispersed by this methodology. Significant improvement in mechanical properties is observed with MWCNT addition, with 940% modulus increment regarding to the pure polymer and also, in lower intensity, in HNBR/FLG composites. Moreover, HNBR/MWCNT composites presented a sharp reduction in electrical resistivity at low loading level.  相似文献

In this paper, the effects of graphene loading and processing technique on the morphological, mechanical, thermal, rheological, and barrier properties of bromo–butyl rubber, are explored. Bromo–butyl rubber composites with electrochemically exfoliated graphene (EEG) nanosheet filler are prepared via solvent casting and/or melt blending techniques, and their properties are compared against a carbon black control sample. Even though analysis of the EEG composites via microscopy reveals agglomeration problems not present in the carbon black controls, EEG composite samples are observed to have improved barrier properties over carbon black samples in exchange for slightly reduced stress and strain at break. Extensional rheological analysis of the bromo–butyl rubber composites reveals strain hardening phenomena in all the samples and higher extensional modulus in solvent casted-melt blended (SCM) samples. As a result of better dispersion over the solely melt-blended samples, the SCM rubber composites exhibit superior tensile modulus and extensional modulus compared to the samples that are solely melt-blended.  相似文献

A functionalized graphene, fluorinated graphene nanosheets (FGS), and SiO2 nanoparticles as reinforcing fillers were employed to improve the mechanical properties of the solution styrene butadiene and butadiene rubber composites (SSBR‐BR). The results showed that the mechanical properties of SSBR‐BR composite filled with FGS were substantially improved than those of the unfilled and equivalent filler loaded graphene oxide (GO) and reduced graphene oxide (rGO) filled SSBR‐BR composites. It can be ascribed to the fact that the hydrophobic surface of FGS can be endowed the good dispersion in rubber matrix and stronger interfacial interaction between rubber and fillers. The tribological properties of these composites are also investigated. The results reveal that incorporation of GO, rGO, and FGS in SSBR‐BR composites can decrease antiwear properties because the existence of layered graphene promotes to tear and peel off. © 2017 Wiley Periodicals, Inc.

Graphene has become an attractive reinforcing filler for rubber materials, but its dispersion in rubber is still a big challenge. In this work, a novel carbon black‐reduced graphene (CB‐RG) hybrid filler was fabricated and blended with styrene‐butadiene rubber (SBR) via simple two‐roll mill mixing. The prepared CB‐RG hybrids had a microstructure with small CB agglomerates adsorbed onto graphene surfaces. CB acted as a barrier preventing the RG sheets from restacking even after drying. Homogeneous dispersion of graphene sheets in SBR matrix was observed by the mechanical mixing method based on the application of the CB‐RG hybrid fillers. Dynamic mechanical analysis showed that Tg of the SBR/CB‐RG blend was higher than that of the SBR/CB blend indicating strong interfacial interactions between RG and SBR due to the high surface area of graphene and the π‐π interaction between SBR and graphene. The tensile properties of SBR/CB‐RG composites improved significantly and the volume resistivity decreased compared with the SBR/CB blends. The thermal stability of SBR composites filled with CB and CB‐RG showed slight difference. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015 , 132, 41309.  相似文献

We report a novel, scalable and inexpensive approach to fully disperse carbon nanotubes in silicone rubber by the addition of graphene. In comparison to graphene, the dispersion of multi-walled carbon nanotubes (MWNTs) in silicone rubber matrix is extremely difficult although both of them possess similar physical structure. The different dispersion behavior of graphene and MWNTs could be contributed to the difference in their interaction with polymer matrix and their geometry. Based on SEM, TEM and XRD analysis, we find that the dispersion of MWNTs in silicone rubber is dramatically improved by the addition of graphene. Graphene acts as a compatilizer since it shows strong interaction with both polymer matrix and MWNTs. This method provides a simple route to enhance the dispersion of carbon nanotubes and improve the electrical property of the polymer composites. The synergic effect of the hybrid materials may not to be limited to the applications in polymer composites.  相似文献
