Need for Modified Epoxy and Modifiers

These drawbacks forced the resecRchers to focus on the modification of epoxy resins using suitable modifiers to overcome the drawbacks mentioned above in order to main-tcun their Vcdid status in the high performcuice polymers. 

Corrosion and fouling pose another serious economic problem to maritime activities. The protective coatings on marine structures get easily damaged within a month s time resulting in direct and indirect loses to a country, which could be as high as 5% of the GNP [18-20]. Literature describes a variety of methods such as immobilization of marine bacteria in hydrogels, and piezo electric and electrolytic techniques for the control of corrosion and fouling [21-25]. However, none of these methods is satisfactory 

With all these ideas in mind, an attempt was made to obtain high performance epoxy resins with superior impact strength, thermal stability, flame retardancy and corrosion and fouling resistance by simultaneous incorporation of silicone and phosphorus moieties into the epoxy skeleton. The present work discusses the development of novel phosphorus-containing siliconized epoxy resins, the improved characteristic properties of the cmed resin systems md their nanocomposites as well. The developed phosphorus-containing siliconized epoxy resins offer multi-faceted properties ideally suitable for high performsmce apphcations.
