Résumé : |
Coatings are nothing but a stable dispersion of various raw materials in a continuous phase which are applied onto the substrates to accomplish both decorative and protective functions. Choice of the functional raw materials plays a key rote in this process. As the coating technology strives to design "Intelligent & Smart" coatings which sense and responds to the changing service dynamics with the aim of enhancing the service life of coatings to Amazonian proportions, it becomes imperative that the raw materials are to be incorporated in such a manner that they remain unaffected for long both in-can and after application, be readily available as and when required to achieve specific tasks, at specific locations. Microcapsules are made by encapsulating the functional materials within an appropriate shell and incorporating them within the paint helps to achieve ail of this and more. Microcapsules helps to preserve the functional materials for as long as they are required, deliver them as and when required and at appropriate locations within the coating matrix — something similar to that of precision guided munitions. This review article guides the reader through the process of micro encapsulation, preparation of micro capsules with elaboration on specific techniques, release mechanisms & profiles and some of the performance attributes they can impart to the coatings and in the conclusive part of this article some of the key challenges that are yet to be overcome are also discussed. |
