Abstract：

Strontium　hexaferrite　nanoparticles　(NPs)　were　prepared　by　co-precipitation　of　strontium　and　ferric　ions　in　sodium　hydroxide　solution.　The　SrFe　12O　19　NPs　were　characterized　by　X-ray　powder　diffraction,　transmission　electron　microscopy　and　vibrating　sample　magnetometer.　SrFe　12O　19　NPs　with　perfect　crystal　structure,　nanometer　size,　high　saturation　magnetization　and　coercivity　were　obtained.　Afterwards,　strontium　hexaferrite　nanoparticles　were　dispersed　in　polyester-polyurethane　solution　to　prepare　magnetic　coatings　(MCs)　via　solution　blending.　The　magnetic　and　rheological　properties　of　magnetic　coatings　were　measured　by　Gouy　magnetic　balance　and　rotational　rheometer,　respectively.　Furthermore,　the　mechanical,　thermal　properties　and　physical　properties　of　magnetic　films　were　also　investigated.　The　results　showed　that　magnetic　films　with　superior　mechanical　properties　could　be　obtained　with　the　addition　of　27　wt%　magnetic　powders.　©　2012　Elsevier　B.V.　All　rights　reserved.
