Co rrosion s tudy of na nocomposite epoxy / steel polyvinyl alc ohol on t he electrode surface

Epoxy has several attractive properties, such as me chanical du rability, har dness, toug hness, and ch emical inertness that complement t he intrinsic characteristics of Polyaniline (PANI). Polya niline (PAN I) is considered a very interesti ng material for electrical or electronic applications, as it combines s tability, conductivity and low cost.[۱] A consequential draw back of the conductive form of P ANI is its p oor mecha nical properties. To tackle this problem, researchers have intensively studied the blends of PA NI with a variety of polymers.[۲] P ud et al.[۳] reviewed the different preparation methods of polyaniline blends and composites with organic polymers. Two gen eral categories of processing met hods can be defined as the follow ing: a) synthetic meth ods, in which the polymerization of aniline t akes place in the presen ce of the polymer matrix, and b) b lending methods, in w hich PANI is mixed with the polymer matrix. B lending methods inclu de the solution blending of PANI w ith polymers and dry blending.
