Infrared Analysis of Electrostatic Layer-By-Layer Polymer Membranes Having Characteristics of Heavy Metal Ion Desalination

Abstract

Layer-by-layer (LbL) self-assembly is a spontaneous and reversible organization process of interacting organic and polymeric components by their aggregation into ordered structures on substrate. LbL self-assembly process which occurs due to sequential adsorption of materials with complementary functional groups. Producing robust films and allow a precise control over the film thickness and its properties. This technique has been widely applied for the fabrication of multilayer films of organic and polymeric compounds, organic-inorganic hybrid structures, larger objects such as latex particles, and even purely inorganic thin films. By combining various functional materials for the formation of self-assembly multilayer, the LbL technique has led to a wide range of novel materials for various applications.[1,2]
