The Structure

The spin SA method has been found to have a significant effect on the surface roughness of prepared multiplayer films, presumably because of the air shear force caused by the spinning process [110]. It was proved that the internal structure of the spin SA films is highly ordered and the film prepared with the spin process contains rather distinct interfaces between respective layers in contrast to the film obtained by the dipping method. The distinct difference in the dip and spin SA multiplayer structure indicates that the spin SA method can easily provide the well-ordered internal structure, which cannot be achieved with the dip SA even containing a high ionic strength of the polyelectrolyte solution or multiple organic layers between inorganic particle layers [112].
