The method of spray drying of the dispersion or emulsion of the encapsulated substance containing polymer and solvent (both organic and aqueous) consists in their dispersion into the flow of a coolant gas. As a result of heat and mass transfer, the solvent is removed from the system and dense particles are formed, the encapsulated...
During microencapsulation by extrusion, a thin viscous film of film-forming material is formed on the surface with small diameter holes, through which the encapsulated substance is pressed. The shell formed in this way is further stabilized by cooling or polymerization of its constituent monomers. For microencapsulation by extrusion, forming devices are also used, which are...
Crosslinking of polymer chains is carried out by introducing special substances into the system, which, as a result of ion exchange, form bonds between two neighboring chains. In this case, the process takes place at the interface of the phases. It is possible to use oil-in-water systems containing a hydrophilic polymer and, for example, lower...
