Resumen:
PVA
ferrogels were obtained by swelling physical hydrogels (synthesized by freezing/thawing
(FT) technique) in Fe3O4 nanoparticles (NPs) aqueous solution. Different
samples were prepared by varying numbers of FT cycles applied (1-4). All
ferrogel samples were studied by thermogravimetric analysis, differential
scanning calorimetric (DSC) analysis, and magnetic measurements. The DSC
results showed the higher the number of FT cycles, the higher the crosslinking
density. The thermograms pointed out that the NPs affect the thermal stability
of each ferrogels. These results reveal that ferrogels might have a potential
for applications in biomedical applications
