Encapsulution of Hydrophobic Materials

Verkapselung hydrophober Materialien

LbL technology is suitable for coating of hydrophobic solids and oil droplets as well. Hydrophilic LbL layers can be formed at the surfaces of hydrophobic materails even without using any surfactants. Coated materials can then be stored in aqueous medium, where they form non-aggregating monodisperse suspensions.
