LAYER-BY-LAYER
TECHNOLOGY
ELECTROSTATIC SELF-ASSEMBLY
The LbL assembly is a multistep process, in which the different electrostatic attraction forces of the polyelectrolyte solutions keep the coating together.
The almost perfect order at the molecular level of the individual monolayers is the result of many individual molecules reaching their minimum energy configurations locally. They are adsorbed from the aqueous solutions and bind with previously fixed molecules to the substrate. The interpenetration of molecules in adjacent layers can be controlled to improve the macroscopic properties of the material.
LbL technique offers some important advantages in comparison with other coating techniques:
Simplicity: It can be used to coat COMPLEX GEOMETRIES with homogeneous results.
Control: LbL allows to control CONTROL THE THICKNESS of the film.
LbL can be used with nanoparticles, polymers, fluorescent indicators and colorimetric compounds.
