Abstract
Graphene and carbon nanotube (CNT) exhibit excellent mechanical, electrical, and thermal properties. In a previous study, these materials were derived from sp2 bonded carbon atoms closely packed in a honeycomb crystal lattice. However, there were several problems with the derived materials including suboptimal mechanical properties, slippage within the graphene surface, leakage CNT from the resin, and lack of bonding between nanomaterials. To address the aforementioned deficiencies, we proposed the fabrication of a graphene CNT hybrid material (G-CNT) consisting of an extensive network of chemically bonded layers. Chemically bonding was performed via dehydration synthesis of amino and carboxyl groups. To analyze the produced material, we employed Fourier transform infrared spectroscopy (FT-IR) and tensile tests. The FT-IR spectra confirmed, amino modification of graphene, oxidation of carboxyl modified CNT, and oxidation of the amide group of G-CNT. The tensile tests, demonstrated that PVA films containing G-CNT have high ductility in comparison to both pure PVA and PVA lacking chemically bonded CNT and graphene.
