Formation and Stability of Polyelectrolyte Multilayers of Chitosan and Poly(acrylic acid)

Abstract:

The article intends to introduce the authors’ experimental study on adsorption behaviour of chitosan and poly(acrylic acid) solution on silica by reflectometry. pH effect on adsorption-desorption of Chitosan and interaction with poly(acrylic acid) polyelectrolyte multilayer on silica has been studied. Builting multilayer formation on silica by 100ppm chitosan and 25ppm Poly(acrylic acid) solution with reflectometer. Effect of ionic strengths and molecular weight of chitosan have been discussed and we built 4 layers chitosan and 3 layers PAA and check BSA adsorption and stability. Atomic force microscopy measurement has been measured in the experiment. The results show adsorption kinetics, adsorbed mass plateau values, and reversibility of the layer formation which is typical for adsorption of strongly charged polyelectrolytes onto oppositely charged surfaces.
