CONCLUSION
The adsorption of polyelectrolytes onto solid surfaces is essential for
scientific and technological purposes, and their understanding is critical
for development new of applications in many fields. The comprehensive
understanding of the physico-chemical phenomena that governs the adsorption
of polyelectrolytes onto surfaces, and the different routes for the modification
of both the dynamics and equilibrium aspects of the adsorbed layers is
essential for the development aforementioned applications. This requires the
study of the intricate balance of interactions involved on the adsorption with
the direct electrostatic interactions and the entropic ones playing the main role.
Thus, the advancement of the theoretical and experimental knowledge on this
field is essential for the development of new applications.
