Electrochemical investigation of the properties of Co doped ZnO nanoparticle as a corrosion inhibitive pigment for modifying corrosion resistance of the epoxy coating

Covalently-grafted graphene oxide nanosheets to improve barrier and corrosion protection properties of polyurethane coatings

“…In addition, it has been reported that nanoparticles provide much better barrier properties than conventional micron size pigments due to their higher surface area. The role of nanoparticles including SiO 2 [14], Al 2 O 3 [15], Fe 2 O 3 [16], ZnO [17], Zn, Si [18,19] and halloysite clay [20] on the corrosion resistance of the epoxy coatings over the steel substrates in NaCl solution has been extensively studied. The results obtained from these studies revealed that the epoxy coatings containing nanoparticles offer acceptable barrier properties for corrosion protection.…”

Investigation of the size effect of graphene nano-platelets (GnPs) on the anti-corrosion performance of polyurethane/GnP composites

“…[14][15][16][17] For instance, polyurethane (PU) and epoxy are commonly used coating materials as the protective layer on metal substrates. [16][17][18][19][20][21][22] PU has especially attracted many researchers because of its exceptional mechanical property as well as an excellent adhesion to the metal. [23][24][25] PU is based on the reaction between the isocyanate (-NCO) group and a polyol including hydroxyl groups (-OH), where the isocyanate group and polyol comprise a hard segment and so segment respectively.…”

Anti-corrosive and oil sensitive coatings based on epoxy/polyaniline/magnetite-clay composites through diazonium interfacial chemistry

“…As α approaches 1, the CPE behavior approaches ideal capacitor behavior. It is worth mentioning that both of CPE1 and CPE2 were used instead of a regular capacitor element, to estimate the value of the coating capacitance (C c ) and the double layer capacitance ( C dl ); using the following formula 77 , 78 . where, Q is CPE constant, α is CPE exponent, respectively.…”
