Radiation Resistant IPN nanoparticle protective coatings for nuclear power plants

Book Summary   by:vidhu     Original Author: Vidhu
ª
 
Radiation resistant thin polymer coatings for concrete and steel structures could be used in nuclear power station as a replacement against the thick polymer coatings presently being used for the protection against radiation. Some of the presently used coatings have certain disadvantages such as they harden, become brittle, shrink, and crack under heavy doses of radiation; while some depolymerise and become sticky and soft; while still others blister and lose adhesion. Interpenetrating Polymer Network (IPN) nanoparticle protective thin coating have superior mechanical, chemical, and corrosion resistant properties; These coatings, therefore, could form a basis for being proposed for such applications. These IPN coating are based on acrylic, vinyl and epoxy combination. Several IPNs based on epoxy-silicone, epoxy chlorinated rubber-silicone etc have been developed and have given promising results for protection to the steel against corrosion.
