Molecular tailoring and engineering of polymer-based materials for marine corrosion and metal ion detection applications

摘要

Corrosion is a long-lasting and challenging issue to modern industrial activities,udespecially to marine and offshore industries. In fact, the costs related to corrosion andudcorrosion prevention is a significant part of the gross national product in the world.udDue to the increasing demand for marine transportation and oil and gas exploitation,udsolving the technological difficulties relevant to corrosion protection is absolutelyudessential. Epoxy resins have become one of the most widely used polymers in coatingudapplications. However, common epoxy resins show undesirable water moisture affinity,udwhich may lower their performance as anticorrosion coatings. Therefore, a series ofudpolysiloxane derivatives have been synthesized and blended with epoxy resins asudadditives. The resulting material has been investigated by various chemicaludcharacterizations and numerical simulation of the cathodic protection system, calledudBEASY. As a result, various analyses confirmed that the performance of epoxy resinudcoatings in terms of corrosion protection was greatly enhanced.
