a) Different raw materials (cork and sea-derived materials) are extracted and fractionated using standard methodologies, such as, Soxhlet extraction;
b) Modification of polymers by chemical processes using different grafting agents;
c) Separation of chemical species by means of chromatographic techniques;
d) Synthesis of new polymeric structures by means of standard chemical procedures and enzymatic approaches;
e) Manipulation of materials for layer-by-layer assembly of polyelectrolytes or other compounds by consecutive dipping in their solutions.
