TECHNICAL DESCRIPTION
The invention describes composite capsules, obtained by interfacial polycondensation, which contain a complexing agent in gel form. Complexing or decomplexing agent properties vary with its chemical nature.
The gel is obtained from polymerisation that allow active principles to be fixed to polymers. Thus metallic ions or organic molecules that go through the membrane are trapped in the polymers. They can remain trapped in the capsule and may be released later. The originality of these capsules is the choice of complexing site which can trap any metallic ion or organic molecules.
They are obtained by interfacial polycondensation. Their membrane can be made of different kinds of chemical natures according to the applications.
