Self-assembly(SA)

a new method of creating ultrathin polymeric nanocomposite films is introduced in this paper

which is based on the electrostatic attraction between opposite charges.In contrast to classic Langmuir-Blodgett and other techniques

films’ good long-term thermal and mechanical stability

relative ease of preparation and high degree of versatility render SA technique amenable to a large variety of diverse polyelectorlyte systems

such as polyelectrolyte- polyelectrolyte

polyelectrolyte-clay platelets

polyelectrolyte-protein

polyelectrolyte-inorganic nanaparticles

and so on.
