The results revealed a synergistic interaction between the GnPs and MWCNTs based on GnPs protection against fragmentation of the MWCNTs during high-power sonication. Chao Zhang et al. [6] revealed that the graphene oxide (GO) assisted the dispersion of pristine MWCNTs

in aqueous media. Moreover, the solubility results indicated that the GO sheets leaned towards stabilizing MWCNTs with larger diameters, mainly depending on whether the MWCNTs are inclined to form bundles, twisted structures, or MWCNTs/GO complexes. S. Chatterjee et al. [4] studied the mechanical reinforcement in a widely used epoxy matrix with the addition of GnPs and various mixture ratios of MWCNTs with GnPs. It had been indicated that the size and synergy effects of nanofiller hybrids including GnPs and MWCNTs AC220 molecular weight played an important role in the mechanical properties of epoxy composites. As mentioned above, these hybrid materials were obtained via the unstable π-stacking interaction, which could be damaged by mechanical stirring or long-time ultrasound. Young-Kwan Kim et al. [7] formed graphene oxide scrolls around MWCNT templates through covalent bond formation. Graphene oxide sheets were successfully made to adopt a scroll conformation around the Tubastatin A supplier surface of aminated MWCNT in solution by covalent bond formation. Like the stick wrapped with a film, the microstructure of this kind

of hybrid material was still two-dimensional (2D) structure. In this work, we chose carbon nanotubes and graphene nanoplatelets

https://www.selleckchem.com/products/H-89-dihydrochloride.html to prepare three-dimensional (3D)-structured hybrid materials. Due to their unique tubular structure, carbon nanotubes mainly reflect rigidity, Ponatinib supplier while graphene nanoplatelets appear to have better toughness owing to its laminated structure [8–10]. A methodology of preparing multi-walled carbon nanotubes/graphene platelets (MWCNTs/GnPs) hybrid materials was proposed, using poly(acryloyl chloride) as bridges between carbon nanotubes and GnPs. Compared with the other hybrid methods [4–7], this approach is facile, efficient, and easy to control by regulating and controlling polymer chains of poly(acryloyl chloride) (PACl) which can provide numerous reactive groups. In addition, based on the theory of hybrid structure [11], this novel kind of MWCNTs/GnPs hybrid materials can combine the advantages of carbon nanotubes and graphenes, which would make this unique hybrid structures possess the potential application in a wide field, especially in increasing the toughness and strength of the matrix resins. The preparation process involved the following three steps: Firstly, hydroxyl groups on the surface of acid-oxidized multi-walled carbon nanotubes (MWCNTs-OH) reacted with linear PACl to generate highly reactive polymer grafting on the nanotube surface [12, 13].
