1. After filtration, the obtained sample was dried in vacuum oven at 70 C and labeled as rGO.2. Generally, GO or rGO prepared by chemical methods is composed of graphitic, oxygen-containing groups and defects.3. Then 50 mL of NaHCO3 (0.029 M) was added with drop by drop to the above solution.4. For comparison, pristine Ag2CO3 and Ag2CO3-GO-1.0 were prepared according to the similar procedure but without rGO or with the addition of 1.0% of GO.5. Simply, the rGO suspension with a concentration of 1.0 mg mL1 was obtained with the aid of ultrasonic dispersion.6. The successful isolation of graphene by the microcleaving of highly oriented pyrolytic graphite (HOPG) has opened up exciting possibilities for experimental investigations. Significant attention has been captured by its outstanding properties which render it another materials option for electronics applications.7. but the intrinsic properties of graphene have not yet been achieved.8. Since the solubility of carbon in Ni is temperature-dependent.9. The transferred graphene films preserve their continuity and attach strongly to substrates made of almost any material, such as semiconductors, glass, metals and plastics, via van der Waals interactions.10. The differences in thickness range from a monolayer to a few graphene layers.11. Efforts are underway to improve the quality of the films by tuning the CVD growth conditions.12. Analogous to the case of carbon nanotube growth,42,43 this technique can potentially enable the simple growth of graphene at particular locations and with desired geometries by controlling the catalyst morphology and position.13. Original graphite is compact and ordered aggregates, and it is hard to disperse into nanosheets in aqueous.14. The enlargededges provide a pathway for oxidants to penetrate into the deeper level.15. which can avoid reunite and achieve GONs uniformly dispersion in cement paste.16. The results have a very positive to application of GONs for reinforcing/ toughening cement composites.17. Graphene oxide (GO) as an important building block for fabricating electronic devices has recently captured considerable attention due to its tunable physical chemical properties by manipulating oxygen-containing functional groups.18. To completely remove the residuals, the wash-centrifugation process was repeated for 5 cycles.19. 3 orders of magnitude higher than that in the water-lean state.20. The in-plane electrical conductivity is much higher than cross-plane electrical conductivity.21. Therefore, we speculate that the epoxide groups play a central role in electrical transport of GOs by influencing band gap, interlayer distance andwater intercalation process.22. We observed that the conduction behaviors can be tuned by manipulating the oxidation degree and water content.23. Our results suggest that epoxide groups make the major contribution to electrical transport.24. The list was presented in order of priority as:25. Another method based on the combustion of benzene in an oxygen deficient environment has been proposed for the formation of C60 and C70.26. Due to extant properties27. Through chemical oxidation treatment, the CNTs could be unzipped to form a ribbon shaped graphene.28. Based on the facts mentioned above, the GNR was potentially a promising alternative since it had desirable properties with many oxygen groups, which could facilitate its dispersion and adhesion with the SR chains.29. TEM observations were performed on an H-800-1 transmission electron microscope (Hitachi Co., Tokyo, Japan) with an acceleration voltage of200 kV to acquire a direct visualization of the dispersionstate of nano particles in the composites.30. Nano-aAl2O3 particles have a huge specific surface area and large surface energy, which will lead to a strong tendency for self-aggregation.31. Generally speaking, dispersion improves with increasing heat-treatment time within a certain range, but the dispersion does not improve further with further increases in heat-treatment time, as shown in Fig. 3c and d.32. which could be attributed to the three-dimensional thermally conductive network constructed by hybrid fillers.33. This unique structure effectively prevents the inter-sheet restacking of graphene sheets and minimizes the thermal contact resistance between fillers and interface. The resultant exhibits a high thermal conductivity of 2.40 6 0.07 W/m K which is much higher than single filler at the same loading. We also believe that the thermal property can be further improved by optimization of the content of hybrid fillers and processing and modification of Al2O3 and GR.34. The extremely high aspect ratio of BNNSs implies that a low loading of BNNSs is sufficient to obtain a desired TC without sacrifi cing other inherent elastomeric properties such as high or low temperature resistance, softness, and elasticity.35. Figure 3(b) shows the scrolling and folding effect of t
