A) Scanning electron microscopy (SEM) image of the coated conductive foam. Samples were prepared by sectioning the conductive foam and observation in the SEM without further sputtering showing an average thickness of the coating layer of ~4.29±0.5µm over the PU foam. B) Microanalysis of the conductive foam was performed clearly showing carbon ‘C’ in coating and PU foam whereas silicon ‘Si’ is only present in the coating due to the silicone elastomer in the conductive ink.
