Corrigendum: Graphene nanoribbon–PVA composite as EMI shielding material in the X band (2013 Nanotechnology 24 455705)

There was an error in calculating the weight percentage of the graphene nanoribbon (GNR) in PVA. There were three films made with different concentrations of GNR. The correct weight percentage of GNR in PVA in three films should be 0.75%, 1.5% and 2.5% instead of 0.0075 wt%, 0.015 wt%, and 0.025 wt% respectively. Reference to the weight percentage has been made in the abstract, line 5; page 3, paragraph 5, second line; page 4, paragraph 1; page 6, paragraph 2, line 6; figure caption 4; figure caption 10 and figures 9 and 10, the corrected versions of which are shown below.
