1. Opening up enormousopportunities to prepare high performance rubber
composites for future engineering applications.
2. In order to tackle this global issue, new oil-independent fillers have
received increasing attentions for replacement of CB.
3. (溶液混胶) However, conventional mechanical blending method cannot
uniformly disperse the GO sheets inthe rubber matrix (see Supplementary Information S10). Solution mixing12–15 has been demonstrated to be aneffective way to obtain the desired dispersion, but the removal of organic solvents poses persistent problems suchas added cost and potential environmental pollution for the practical implementation of the method.
4. The GO/SBR composites formed by this route exhibit
unprecedentedreinforcing efficiency of GO towards SBR
5. The GO dispersion in composite and the interface interaction are thetwo
main factors to determine the reinforcing efficiency of GO in thecomposite.

haveepoch-making significance(划时代的)in the oil-dependent rubber industry.
7. As shown in Fig. 4e, the storage modulus of theSBR/GO composite
increases with the GO content increasing,throughout the range of temperatures investigated, indicating thatthe elastic response of neat SBR towards deformation is stronglyinfluenced by the presence of nanodispersed GO sheets.

15. And their synergistic effect in enhancing the properties of poly(vinyl
alcohol) (PVA) nanocompositeswas investigated.

avoiding the agglomeration phenomenon of nanofillers within the polymer matrix, resultingin nanocomposites with largely enhanced properties compared to those prepared from single nanofiller(CNC or GON).
17. Recently, hybrid reinforcements of polymer nanocomposites are
gaining increased acceptance.
18. in order to understand the synergisticeffect generated from the

(确定)the
influence ofthe irradiation on the oxidation index

26. The CNTs had several tens of micrometers in length and 50–200 in
diameter.
27. Among them, nanotubes and grapheneare the most dazzlingstars in
the field of nanotechnology.
28. Compared toCNTs, graphene, a two-dimensional (2D) hexagonally
atomic carbon film, also possesses the above mentioned properties of CNTsas well as its special features, e.g., high light transmittance [8]and high reactivity of graphene edges [9], and has shown greatcharm in nanocarbon family.

1CNT interlayers.
34. The elemental mapping of interlayersafter cycles was carried out on
an energy dispersive spectrometer(EDS) linked to SEM 6390.
35. Physical and chemical vapor deposition methods to synthesizethin
films are also described quite often but all of them aredogged by (受困
于)the elimination of the very stable N2, which results indisordered,
quite carbon-rich materials.
36. Thermoanalyticalmethods (TGA, DSC) in combination with
XRD were used to characterize the intermediate steps along the condensation of the molecular precursor.
37. However, the principal difference between the graphene and
MWCNT lies in their shapes. Graphene has a plate-likeshape and is bi-dimensional, whereas MWCNTs are uni-dimensional with high aspect ratio.

47. The reduced graphene oxide (RGO) wasalso prepared in similar
procedures in the absence of Fe3O4 toperform a contrast experiment
48. Unfortunately, the impact strength of the composites declines when
theamount of fillers is further increased, which is due to the fact thatexcessive fillers can not be well dispersed in the BMI matrix andagglomerate to cluster.

contrast in Fig. 2B. It clearly exhibited the lattice fringes with a d spacing of 0.203nm, corresponding to the interplanar distance of(110) planes of metallic Fe. Energy dispersive X-rayspectroscopy (EDS)
measurements also e videncedthe existence of element iron and nitrogen (Fig. 2E).The signal of element copper in Fig. 2E should befrom copper grid used for TEM observation.

room temperature with excited laser wavelength and power density of1064 nm¢1 and 5 mWcm¢2, respectively (Figure 1A). The Dband in 1281 cm¢1 derives from the amorphous carbon anddefects, while the G band in 1589 cm¢1 indicates the graphitelayer of CNTs.[22] The intensity ratio of defect-derived D band(ID) to graphite-derived G band (IG) reflects destructiveness ofthe SP2 hybridized carbon atom. Thus, the increase of theID/IG ratio is an indication of the destructiveness or the defectformation of the CNTs surface.
66. (XRD说法)The crystallinenature of Pd NPs was confirmed
by XRD (Figure S3, SupportingInformation). The peak at 25.98 is attributed to the hexagonalcarbon structure of CNTs in (002) plane.[32] The 2q values of40.08 correspond to the diffraction peaks of Pd (111) with dspacing of 0.23 nm, while 2q value of 46.38, 67.88, and 80.68correspond to Pd (200), Pd (220), and Pd (311), respectively.
67. In addition, the Pd (311) diffraction peak for Pd-CNTs-1 and
Pd-CNTs-2is discernible but of much low intensity, which may be due tothe fact that···········
68. Pd NPs with controlled particle size have been uniformly assembled
and anchored on the surface of CNTs .
