Ev aluation of corrosion rate of nanocomp osite epox y / polyvinyl alcoh ol - Poly aniline on t he electro de surface iron

Electrically conductive adhesives based on Nano polymer–metal composite /Epoxy . Tri Etyhle ne Tetramine (DGEBA.TETA) system containing poly vinyl alcohol/epoxy and differe nt metals (copper, nic kel and sil ver) nanoparticles com posite materials have been succes sfully developed and characterized . The blen ds were prepared by ph ysical mixing of Nano poly vinyl alcohol/epoxy composite within poly vinyl alcohol/epoxy matrix. The physic al mixing procedure c ontributes f or the formation of a c onducting pathway with the lower amount of p oly vinyl alcohol/epoxy properties were achieved with these systems [۱ -۴].
