Design and fabrication of the laponite barrier layers atop a GS-containing polymeric multilayer film: (A) Schematic of the spray layer-by-layer assembly of barrier layers on top of the GS dip-LbL films. (B) Atomic force microscopy (AFM) height and phase images of (i)–(ii) no-barrier GS film (G20) and (iii)–(iv) barrier GS film (G20L10), respectively. In the phase images the stiff laponite particles appear bright while the soft polymer appears dark. Corresponding images confirm the successful deposition of barrier layers atop GS films.
