Polyelectrolyte layers of self-assembly technology (layer-by-layer self-assembly, LbL SA), due to the preparation method is simple, rich film-forming material, the film is not a substrate size, shape, and restricting the types of, and has good stability , the film thickness and structure of nanometer range controllable advantage of having a wide range of applications in the field of drug release, sensors, solid state-based batteries, micro-optical device, and the membrane separation. This article polyelectrolyte poly (ethylene-alt-maleic acid) having an optically active R-1-4-methoxy group phenethylamine derivative (PEMA-PMEA) and poly (allylamine hydrochloride) (PAH) build material having an optically active multilayer film of the assembled condition of the amount of the multilayer film assembly, and to explore their growth mode. The functional multilayers development, of polyelectrolyte multilayers applied research has a guiding role. Firstly, the use of poly (ethylene-alt-maleic anhydride) with an amidation reaction between the chiral compound R-1-4-methoxy phenethylamine, synthetic polyelectrolyte having an optically active poly (ethylene-alt-maleic acid) R-1-4-methoxy phenethylamine derivative (PEMA-PMEA). Different degree of substitution of optically active polyelectrolyte prepared by controlling the reaction conditions, the use of UV, IR, NMR, fluorescence and circular dichroism characterization of the structure and nature of the product. Secondly, through the the PEMA-PMEA and PAH electrostatic interaction, the use of layer-by-layer assembly technology to build polyelectrolyte multilayers, optical quartz plate, the use of UV-Vis, fluorescence and circular dichroism tracking to determine the amount of multilayer films assembled change was observed by atomic force microscopy (AFM) the surface of the multilayer film structure. Also investigated the assembly on the assembly and performance of polyelectrolyte multilayers. Finally, we explore the different modes of polyelectrolyte multilayers assembled growth, and the introduction of the multi-layer film assembly changes in unified mathematical equations for describing the multi-layer film growth mode differences in the basic physical and chemical reasons, the model parameter q and m Analysis of the assembled condition, the amount of the membrane assembly wherein q and m represent the growth rate of the exponential and linear growth phase multilayer film. The low concentration of polyelectrolyte multilayer film (0.1mmol / L, 0.2mmol / L, 0.5mmol / L), PAH / PEMA-PMEA in the 225nm absorbance values ??with the double layer between a linear relationship. The polyelectrolyte concentration (1 mmol / L, 2 mmol / L, 5 mmol / L, 10 mmol / L), PAH / PEMA-PMEA assembled multilayer film several Duplex in between 225nm absorbance values ??with double the number of Movement The exponential growth, and subsequently converted into linear growth. The parameters q and m are with the polyelectrolyte concentration increases. Within a certain concentration range, With assembled Solution Add NaCl concentration increases, the multilayer film UV absorption enhancement parameters q and m are with the salt concentration increases, indicating that the higher the salt concentration, the faster the speed of the growth of the film . Assembly solution pH near the pKa of the PAH multilayer film regression parameters parameter q and m with the pH value increases, indicating that the assembly of pH on the growth of multilayer films have a certain influence.
