Abstract
The electro-static self-assembly (ESA) process has proved to be extremelysuccessful in creating multilayer coatings with properties that can betailored for particular applications. In this process, almost any surface withcharged functional groups can be used as a substrate. Alternate dipping insolutions having ions of opposite charge builds up the layers throughionic bonding. One particular application of this process could be to formmulti-functional biocompatible coatings on microelectromechanical systemsdevices intended for use in vivo. In this paper, we describe two differentmodels of the process based on the cellular automata techniques usedin the field of artificial life. The output of the models consists of threeparameters as a function of layer: ionic coverage, film height and filmroughness. The results of the models are compared to experimental data todetermine which of them more accurately describes the ESA process.
