I have successfully green-synthesized Mn3O4 nanoparticles from watermelon rinds extract. Upon calcination, the hydrophilicity of the green-synthesized nanoparticles becomes poor. With this, I plan to improve hydrophilicity by applying surface modification with polyacrylic acid (PAA) as an added capping agent to my synthesized nanoparticles. I am aware that with green synthesis, the flavonoids and other components of the plant extract are naturally capping the synthesized nanoparticles.
Will it be possible just to add PAA on top of the flavonoids present on the surface that caps the nanoparticles?
Hi Gelo, Good day!
Generally, any surface modification would like to consider/ screen for a common media materials/solvents, which is serving well to interface coat-stuff for you is PAA and NPs.
To ensure the PAA is providing good & strong chemical-affinity of contact w.r. t. the surface of targeted-NPs.
Hope will help in your study.
Good luck.

Dear global
Yes Its possible.
By adjusting the pH of the reaction solution, you can modify the surface morphology.

Flavonoids at reduction with atomic hydrogen in the presence of magnesium
(or zinc) and concentrated hydrochloric acid form a characteristic colour. The reaction is very sensitive, based on carbonyl reduction groups and the formation of salts of anthocyanidins. They are more hydrophilic.
