摘要：
This study elucidates the tunability of the magnetic properties of cobalt spinel ferrites embedded in a polyvinyl alcohol (PVA) hydrogel by changing the structure of the polymer network. We report on the preparation and characterization of sPS-Co Fe2O4 ferrofluid and PVA/ sulfonated polystyrene (sPS)-CoFe2O4 ferrogels obtained by submitting the samples to a different number of freezing-thawing (F-T) cycles. The magnetic properties were evaluated and interpreted as a function of the PVA/sPS- CoFe2O4 composition and final structure of the ferrogels. © 2007 Materials Research Society.
