摘要: Abstract Graphene/carbon nanotubes (G/CNTs) hybrid fillers were synthesized by γ -ray radiation reduction of graphene oxide (GO) in presence CNTs. The obtained with three-dimensional (3D) interconnected network structure characterized X-ray diffraction (XRD) and scanning electron microscope (SEM). Poly(vinyl alcohol) (PVA) composite films enhanced mechanical properties thermal stability subsequently prepared solution blending G/CNTs PVA matrix. tensile strength Young's modulus containing 1 wt% measured to be 81.9 MPa 3.9 GPa respectively, which 56% 33.6% higher than those pure PVA. These substantial improvements could attributed the 3D G/CNTs, homogeneous dispersion as well strong hydrogen-bonding interaction between macromolecular chains.
