NANOCAPSULES HAVING A POLYELECTROLYTE ENVELOPE

A method for the production of nano- or microcapsules having a diameter of from 20 nm to 40 μm is suggested, wherein template particles are supplied in an aqueous medium, electrically recharged with a polyelectrolyte, re-recharged without separation or washing steps using a second polyelectrolyte ha...

More Information
Summary:A method for the production of nano- or microcapsules having a diameter of from 20 nm to 40 μm is suggested, wherein template particles are supplied in an aqueous medium, electrically recharged with a polyelectrolyte, re-recharged without separation or washing steps using a second polyelectrolyte having a complementary charge with respect to the first polyelectrolyte, and said process is optionally continued with alternately charged polyelectrolytes.
