The invention relates to Nano- or microsized containers comprising either a water immiscible or sparingly miscible core dispersible in aqueous dispersion medium or a water miscible core dispersible in non-aqueous dispersion medium and a core-soluble active agent which is selected from the groups of corrosion inhibitors, catalysts, accelerators of catalysts, adhesives, sealants, polymerizable compounds (monomers), surfactants, lubricants, antifouling agents, water repelling materials or their mixtures, and a stimulus- sensitive polymer/polyelectrolyte shell which is capable to encapsulate the core-soluble active agent and release the encapsulated agent in response to an external stimulus, in particular selected from the group consisting of humidity, ionic strength, pH, temperature, mechanical stress, constant and alternating magnetic or electromagnetic fields, corrosion products, electric current, and electrochemical potential. The invention also relates to feedback active coatings comprising said containers which have a broad range of application and can be used, for example, in the field of corrosion protection of metals, protection of wet surfaces from fouling, or production of new water-repelling materials for textile industry. |
