Introduction Self-healing materials are being developed to improve the lifetime of materials used in various applications including coatings, adhesives, structural components, and even microelectronics. The approach of using microencapsulation for self-healing has been particularly promising with proven success in coatings and in bulk epoxy. However, the size of microcapsules limits their use t...

The effects of epoxy-polyester based powder coatings on the mechanical properties plates made rolled steel sheets were investigated in this work. effect order 100 µm thickness specimens 0.7-1.5 mm thick was considered. Tests carried out at room and elevated temperatures showed that thin had an insignificant bend tensile tests. In particular, bending stiffness is virtually unchanged presence coa...

Graphene is one of the most significant carbon nanomaterials, with a one-atom-thick two-dimensional nanostructure. Like other nanocarbons, graphene has been used as polymer reinforcement. This review explores impact and graphene-based nanocomposites on aerospace applications. The fabrication indispensable features graphene-derived have considered. Numerous polymers employed for systems such rei...

Objective(s): Antibacterial and antifungal nanocomposites are widely used in food packaging and pharmaceutical and medicine industries. Among the polymers of these nanocomposites, epoxy coatings are commonly used for health and industrial applications. The present study aimed to synthesize CuO nanoparticles using the chemical reduction method and characterized them by ultraviolet-visible (UV-Vi...

Corrosion is a primary factor compromising the safety and service life of steel structures. protection coatings are generally employed for structures that exposed to different aggressive environments. This research evaluated use biobased ion exchangers as sustainable means improving corrosion coatings.
 Two base polymer (vinyl coal-tar epoxy) were considered. The following types dosages in...

In the present work, attempts were made to investigate the reinforcement and treatment effect of GF on morphological and rheological behaviour of GF/epoxy vinyl ester composites. GF was incorporated into epoxy vinyl ester resin by sonication, and mechanical agitation. Rheological and morphological properties were studied as a function of particle treatment and size distributions. The dispersion...

in this research, mesoporous silica was applied as the host of corrosion inhibitor (molybdate). the loaded mesoporous silica was dispersed in an epoxy matrix. the composite was then coated on the mild steel plate. results showed that the corrosion resistance of the scratched epoxy/mesoporous silica loaded by molybdate was better than the one without molybdate or neat epoxy. on the other hand, e...

Abstract Nowadays, the recycled fine aggregate sourced from construction and demolition waste is not frequently used in manufacturing of epoxy resin coatings. Therefore, main novelty article to prepare green coatings modified with a replacement ratio natural ranged 20 100%. The microstructural properties aggregates were analyzed using micro-computed tomography, scanning electron microscopy nano...
