This study, magnetite nanoparticles prepared by coprecipitation of FeCl3 and NaHSO3 with NH4OH in distilled water. And then, amino-silane was modified onto the surface of the magnetite nanoparticles to from well-dispersed magnetic nanoparticles. And for new vinyl magnetite momomer (CH2=CHCONH-(CH2)3-Si-magnetite) was synthesized, used to acrylic acid monomer. Pure magnetite, amino-silane modified magnetite, vinyl magnetite were prepared by characterization by XRD, AFM, FT-IR. And we prepared poly(vinyl magnetite-co-acrylic acid) hydrogel. Vinyl magnetites were adjusted to 0, 1, 2 wt% of total acrylic acid monomer. Then we measured swelling ratio and mechanical properties. |
