Adsorption of Fe(NO_3)_3onto Activated Nylon-6,6 as a Container and aPossible 'Smart' Corrosion Inhibitor-containing System

摘要

Nylon-6,6 exhibits chemical, thermal and mechanical propertieswhich include resistance to chemical attack, electrical insulating properties anddegradation resistance. As a possible container, it can be used to manufacture anew family of active hybrid materials, coatings and corrosion inhibitor-containingsystems. The release of encapsulated corrosion inhibitors is triggered by thecorrosion process itself, which prevents the spontaneous leakage of such inhibitorand provides a quick response to changes in the service environment. With this inmind, nylon-6,6 pellets were activated using either γ-irradiation or chemical attackin alkaline solution. Better pore formation was achieved employing the lattermethod, with such pores being filled with adsorbed ferric nitrates. Electrochemicaltests were undertaken to demonstrate the performance of the "smart" nature of thecorrosion inhibitor system formed.
