A composite material (101) is produced by obtaining a plurality of agglomerates (102), introducing the plurality of agglomerates into a liquid carrier including a component capable of solidifying to produce a solidified polymeric material and mixing the plurality of the agglomerates into the liquid carrier (103) to produce a composite material. Each agglomerate is pre-formed by obtaining a plurality of electrically conductive or semi-conductive particles, mixing the plurality of electrically conductive or semi-conductive particles (201) in a granulation vessel. The mixing step includes operating the granulation vessel (202) at a Froude number of between 220 and 1100 and adhering the plurality of electrically conductive or semi-conductive particles by adding a granulation binder to a plurality of agglomerates.

A method for encapsulating active ingredients in liposomes having an active ingredient solution encapsulated with a bilayer composed of two monomolecular layers of amphiphilic compounds comprises: (a) providing the active ingredient solution; (b) providing an emulsion by emulsifying the active ingredient solution in a first liquid in the presence of the amphiphilic compound; (c) providing a liquid phase; (d) contacting the emulsion with the liquid phase to form a phase boundary; and (e) centrifuging the emulsion and the liquid phase that are in contact with one another via the phase boundary, wherein, on passage of the phase boundary, the amphiphilic compound enriched there is added onto the monomolecular inner layer to form a monomolecular outer layer, in order to create the bilayer.
The first liquid of the emulsion is chosen such that the solubility of the amphiphilic compound in the first liquid is not more than 1×10.sup.−4 mol/l.
