This unprecedented ability to fine tune a multilayer to be either cell adhesive or bioinert along with the unique feature of controllable porosity allows polyelectrolyte multilayers to be envisioned for membranes controlled release and biocompatible implant coating applications.
The ion pairing interactions within polyelectrolyte multilayers pemus are reversibly broken by adding salt to the electrolyte in which the pemu is immersed.

Such coatings or films are denoted henceforth as polyelectrolyte multilayers pems.
Thus the bulk modulus of these ultrathin films may be regulated without changing temperature.
Two flexible oppositely charged polymers can form liquid like complex coacervate phases with rich but poorly understood viscoelastic properties.
They serve as an experimental model system for many biological and man made materials made from oppositely charged macromolecules.
