Resumen:
The objective of this project is the intelligent utilization of the biomass to obtainbiodegradable polymers with functional applications of high added value. This requires the developmentof thin multilayers bio-films formed by assembling layer by layer of natural polymers with oppositecharges, with special emphasis in pH and ionic strength sensitive systems. We selected chitosan as macrocationand alginate as macro-anion.This work envisages the development of multilayer thin films using a substrate that can be removed tomake possible the obtaining of freestanding films (as opposite to the coatings reported in the literature)and to carefully analyze the changes induced by modifying variables for preparing the films (depositiontechnique, pH solution, time, number of layers, etc.).
