Paper Title:
Anticorrosive Properties of Epoxy/Polyurethane IPNs Coatings Modified by Organic Montmorillonite
  Abstract

Epoxy/polyurethane interpenetrating polymer network coatings(EP/PU IPNs) modified by organic montmorillonite(oMMT)were prepared by interpenetrating polymer technology and in situ intercalative polymerization methods. TEM analysis showed that there is interaction between the oMMT and EP, PU phase, and the oMMT plays a role of "cross-linking point", changing the EP/PU matrix microstructure. Electrochemical analysis showed that oMMT and IPNs of EP and PU exhibits synergistic effect on improving anticorrosive properties of pure EP. When PU content is 30%, oMMT content is 3%, the EP/PU IPNs coatings has the best corrosion resistance.
