enhanced mechanical, anticorrosion, and antimicrobial properties of epoxy coating via pine pollen modified clay incorporation

In this study, pine pollen (pp) was introduced into the structure of sodium montmorillonite (na+-mmt), and then these new nanoparticles (pp-mmt) were added to the epoxy resin (ep), and new nanocomposites were prepared. the results of the pp-mmt investigation confirmed the presence of pp in the structure. the results of polarization and salt spray tests showed that the presence of pp-mmt in the matrix improves corrosion resistance, so the coating containing 1.5wt. % pp-mmt showed an inhibition efficiency of about 87%. the storage module (e’) for ep was 2170 mpa, which increases with increasing pp-mmt content up to 2350 mpa, also the effect of pp-mmt on the glass transition temperature (tg) was up to 2.5 °c. also, the strength and young’s modulus increased up to 13 and 126 mpa, respectively. moreover, the antimicrobial results showed that the presence of pp-mmt made the nanocomposite effective against bacillus subtilis, staphylococcus epidermidis, escherichia coli, and shigella dysenteriae.
