In an effort to develop a novel graft and new intellectual property, you are considering modification with a polyelectrolyte multilayer made of poly(sodium 4- styrene sulfonate) and poly(allylamine hydrochloride). Explain how this can be done via layer-by-layer deposition. Assume that your graft material has been treated so that the surface is cationic. Please clearly state the order of the poly(sodium 4-styrene sulfonate) and poly(allylamine hydrochloride) layers deposited on the modified surface.
