“…Imidazoles are used primarily as accelerators in reactions between epoxy resins and other curing agents. They can also be used as the sole curing agent [69]. Tertiary amines are also commonly used as accelerators for other epoxy resin curing agents.…”

“…2) would produce branches through mechanisms (i) and (ii), and disturb crosslinking formation, producing a less rigid chemical structure. This was named by Hsu et al [33] as nanostructured ether crosslinked domain. Except for the composition with 4.0 phr of C 4 MImCl, where excess IL yielded a plasticizing effect [31], no significant changes in T g of epoxy occurred.…”

Although epoxy resins are used in a broad variety of applications due to their good mechanical and thermal properties, their low fracture toughness is a limitation, exhibiting brittle behavior. This study explored the potential use of imidazolium ionic liquids (IL) as toughening agents for epoxy resin based on diglycidyl ether of bisphenol A (DGEBA) with triethylenetetramine (TETA) as curing agent. Fracture toughness was evaluated for DGEBA-TETA epoxy resins with eleven imidazolium IL and the best results were found for the IL with the chloride anion and the shortest N-alkyl side chain, C 4 MImCl. The use of 1.0 phr of C 4 MImCl lead to the reduction of the crosslink density of the post-cured resin, resulting in the increase of 25.5% in stress intensity factor and 8.2% in tensile strength with no significant loss in other mechanical properties.

“…29,30 Generally, its specifications depend on the type of resin, functionality of monomers, and the hardener. 31 Bisphenol A is the most common type of linear EP resin. 32 NPs modified EP coatings in some cases show lower resistance to erosion/wear in comparison with the unmodified one.…”

Offshore pipelines are vulnerable against erosion/wear deterioration mechanisms that can be controlled through the use of proper surface coatings, such as polymer matrix nano-composite (PMNC) coatings that are well-known for their ease of production, availability and applicability. Epoxy, as a versatile rigid and brittle resin and polyurethane with proper chemical/mechanical properties, are potential candidates to make the matrix of these composites. A combination of these polymers can also enhance the mechanical behaviors, glass transition temperature and flexibility. In addition, the desired coating characteristics, such as adhesion to metal substrate, mechanical properties, erosion/wear resistivity and UV absorbance, can be further improved through the addition of appropriate nanoparticles within the polymer matrix. Especially, nanoparticles can improve the erosion/wear resistance of polymers because of establishing high strength bonds between the polymer chains and the reinforcements besides enhancing other required properties. The present work is a review on PMNC coatings that contain epoxy, polyurethane or EP/polyurethane as a polymer matrix along with the details of the nanoparticle reinforcements, such as alumina, silica, titanium oxide, zinc oxide, clay and carbon-based materials. The effect of these nanoparticles on the properties of composite coatings has also been investigated.
