Dispersing nanoparticles in a polymer matrix is intrinsically challenging due to unfavorable entropic interactions between the matrix and the nanoparticle. In this research dispersion of nanoparticles in polymer matrix was studied and the effect of dispersion on properties was investigated. The properties of polymer composite depend on the type, size, shape, concentration of nanoparticles, and ...

Abstract In the present work, nano-Aluminum oxide (Al2O3), nano-Silicon Carbide (SiC), or a hybrid of them were infused into epoxy resin with an ultrasonic system various weight percentage ratios nanoparticles. Small punch testing (SPT) and indirect tension adopted to measure tensile properties nanocomposites. Pin-on-ring wear was also performed examine performance Al2O3 SiC The Finite Element ...

With the rapid evolvement of wireless communication technologies, ever increasing needs to prevent electromagnetic waves (EMWs) pollution have urged development lightweight materials with excellent interference (EMI) shielding property. However, achieving desired EMI performance often requires high loadings conductive nanofillers, like graphene, which poses challenges control nanoparticle dispe...

Corrosion resistance of metals is one the most important topics for researchers. In this work, epoxy-TiO2 nanocomposite has been developed protection 6061AL alloy. The dip-coating technique used to deposit coating on 6061 Al alloy substrate. Different concentrations TiO2 NPs (1,3,5 )Wt% have study corrosion behavior in 3.5% NaCl medium. Also, 200,150 and 100 mm/min dipping speeds employed 1%wt ...

The multifunctional novolac epoxy/Al 2 O 3 nanocomposites were fabricated by high-speed mechanical mixing of epoxy resin with varying concentration nano Al (0–5 wt%) particle size 13 nm for 30 min, followed curing triethylenetetramine (TETA) at 110°C 1 h and post-curing 80°C 5 h. nanocomposite samples characterized properties (viz., tensile strength, elongation-at-break, impact toughness, hardn...

This work reports the self-healing behavior of epoxy-based double-layer nanocomposite coatings designed to mitigate corrosion in various industrial applications. Zirconia (ZrO2) nanoparticles were used as a carrier load separately agent, polyethyleneimine (PEI), and inhibitor, imidazole (IM). The loaded ZrO2 with IM PEI doped into epoxy matrix applied on polished steel substrate form pre top la...

Epoxy is extensively used for anti-corrosion coatings on metallic materials. Conventional epoxy have a permanent crosslink network that unable to repair itself when cracks and damages occur the coating layer. This study aims develop self-healing vitrimer/carbon nanotube (CNTs) nanocomposite coating. Two bio-based curing agents viz., cashew nut shell liquid (CNSL) citric acid (CA) were employed ...
