Flake-Filled Polymers for Corrosion Protection

This article provides an overview of polymers reinforced with impermeable flakes that have long been used in the chemical process industry for protecting metal and concrete structures against corrosion. Reviewing the function of impermeable flakes in the anticorrosion performance of polymer composite coatings and linings could serve as a guiding perspective for future studies and extended applications of current polymer-layered silicate nanocomposites in this field. This brief article describes the theory behind barrier improvement in polymers by flake reinforcement, describes ways of evaluating the anticorrosive properties of flake filled polymers reported in recent studies, and reviews some existing applications of flake filled polymers for corrosion protection in the field of chemical processing.
