“…On curing, the epoxy resin forms a network with diferent curing elements like anhydrides, amines, thiols, etc. [2][3][4][5][6][7][8]. Te characteristic makes epoxy resin more efective in diferent usages like coating for protection, electronic usage, fooring purposes, painting etc.…”

This research work developed a method for the analysis of epoxy matrix nanocomposites used in epoxy resin with the incorporation of Al2O3 and SiO2 nanoparticles. The different tests were performed in order to derive the mechanical characteristics and wear properties of Al2O3 and SiO2 nanoparticles. The mixing is performed using an ultrasound process where the nanoparticles are mixed with the resin for a homogeneous diffusion. The strengths observed for the nanocomposite were higher for bending and impact strength because of the Al2O3 and SiO2 nanoparticle incorporation. The wear rate and friction coefficient is observed to be reduced due to the incorporation of Al2O3 and SiO2 nanoparticles into the epoxy resin. This characteristic has a significant benefit of using Al2O3 and SiO2 nanoparticles for loading conditions. The effects of Al2O3 and SiO2 nanoparticles were more effective in epoxy resin, which were more effectively been derived by reinforcing methods.

“…Commercially available nano-TiO 2 can be easily obtained and employed in the production of reinforced coatings. Adding TiO 2 to organic coatings can improve the mechanical properties of the coating 14 and enhance the hydrophobicity due to the increase in nanoscale roughness, thereby improving the corrosion resistance. [15][16][17] In recent studies on the application of TiO 2 in WEP, [18][19][20][21] there have been no reports on polyvinylpyrrolidone (PVP) modified TiO 2 and its application in the field of anticorrosion.…”

Waterborne epoxy (WEP) resins have garnered significant interest due to their potential application as anticorrosion coatings for steel materials. However, it has been reported that defects in the cured coatings generated during the curing process lead to the level of anticorrosion not meeting the expected effects. In this study, TiO2 and GO were selected to be modified by polyvinylpyrrolidone (PVP) to obtain PT and PG, and used to improve the anticorrosion performance of WEP. The obtained PT and PG were characterized using Fourier transform infrared, Raman, and x‐ray photoelectron spectroscopy. The morphology of PT and PG before and after modification was observed using scanning electron microscopy, and the differences were described. The analysis results of laser confocal scanning microscopy and water contact angle (WCA) indicate that there are differences in surface roughness and WCA of the WEP coatings with or without PT and PG. Electrochemical impedance spectroscopy was used to evaluate the anticorrosion performance of the coatings. The results showed that WEP coatings containing PT and PG exhibited better anticorrosion performance. The synergistic enhancement of PT and PG on the anticorrosion performance was proposed, which can be attributed to the comprehensive effect of the hydrophobicity of the coating surface and the barrier effect of PT and PG within the coatings.

We investigated the effect of starch modification on the mechanical properties of phenolic epoxy resin (EP). Corn starch admixture of 2.5, 5, 7.5, and 10 wt% were added into the EP. The tensile strength, elongation at break, and elastic modulus of different corn starch contents were compared. The containing of corn starch showed a positive effect on the toughness of the epoxy but showed little effect on strength when the additive content was less than 10 wt%. The strength and elastic modulus increased first and then decreased with the increase in starch content and reached their maximum values at a content of 2.5 wt%. The enhancement effect might be due to corn starch’s mechanical properties, dispersibility, and interfacial interaction. With the increase in starch content, starch granules quickly contact each other, causing self-aggregation sedimentation and a decrease in strength and elastic modulus. The scanning electron micrographs of the toughened EP specimens showed ductile failure because of the starch particles. The surface morphology of the blend resin specimens was full of staggered and stepped cracks caused by the shearing damage, which is shown by obvious plastic fracture characteristics with plastic deformation ability. The initiation of micro-cracks in the EP matrix was induced by the incorporation of starch particles, which caused localized stepped shear damage in the matrix. More energy would be absorbed during this process, and the toughness of the EP would be enhanced. It is recommended that the best corn starch content should be 2.5 wt% to obtain excellent strength and good toughness.
