<p>Carrier material, at least comprises: (a) an inert carrier core, which exhibits a surface with a positive or negative total charge; (b) a first layer made of first polyelectrolyte, arranged on the inert carrier core; (c) a second layer made of second polyelectrolyte, arranged on the first layer made of first polyelectrolyte. The first polyelectrolyte exhibits a total charge of same type as the surface charge of the inert carrier core. The second polyelectrolyte exhibits a total charge of same type as the total charge of the first polyelectrolyte. An independent claim is also included for preparing a carrier material comprising: (i) providing the inert carrier core, (ii) providing the first polyelectrolyte, (iii) coating the inert carrier core with the first polyelectrolyte, (iv) providing the second polyelectrolyte and (e) coating the inert carrier core, coated with the first polyelectrolyte, with the second polyelectrolyte.</p> |
