As such, the effect of the α-Al 2 O 3 substrate on the surface charge of the composites may be significant for these composite membranes; it seems that, due to the significant thickness of the GO laminates, Al 2 O 3 effects are masked by the strongly ionizable character of the GO’s oxygenated groups.
