“…Further researchers have noticed a significant difference in the surface properties of polymeric films fabricated using DA-, SA-, and SP-LbL methods, which is due to the difference in adsorption mechanisms involved. In DA-LbL, the polyelectrolyte deposits on the substrate as a result of electrostatic interactions, followed by rearrangement of adsorbed polymeric chains. , On the other hand, in SA-LbL, polyelectrolyte deposition and rearrangement occur simultaneously as a result of the high spinning speed. Here, elimination of loosely bound polyelectrolyte chains with water during rinsing also takes a short time as a result of the high spin speed. , In addition, the centrifugal and air shear forces involved in SA-LbL increase the electrostatic interactions, resulting in smoother films compared to the DA-LbL deposition process. ,, Whereas in SP-LbL, the thickness and composition of PEM depend upon the amount of spray that impinges on the substrate.…”
