Graphene (GP) is reinforced with Nylon 6 (PA6) composites were synthesized by melt mix extrusion and moulded through microcellular injection technique. PA6/GP nanocomposites were fabricated for adsorption application for removal of Cd(II) metal ion. The structural morphologies of all samples evaluated on X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), and TGA illustrated the thermally stable, and crystallized materials with pore-like cells. Scanning Electron Microscopy (SEM) analysis at low magnifications showed neat PA6 experienced porous-like fracture and had rough surface after introduction of foaming agent, whilst nanocomposite (PA6/GP) samples had rough, grainy surface indicating extensive deformation within the matrix complex. The storage modulus can exhibit the stiffness of the material and tan δ indicates the glass transition temperature of the composites. The storage modulus is 2399, 2622, 2775, 3221 MPa at 60℃ for the neat PA6, 0.5, 1, 3 wt% GP, respectively. Furthermore, the removal of Cd(II) with PA6/GP 3.0 wt% composite was found to follow the Langmuir isotherm model with a 99.9% removal efficiency. The results indicated that PA6 1.0 wt% composite can be efficiently used as a superabsorbent for the removal of Pb(II) from aqueous solution.
