Studies of Particulates and Structural Transformations in Glass Using Synchrotron Radiation. Final Technical Report
The initial study on nanoparticles of magnetite was carried out in an epoxy matrix. The formation of agglomerates of Fe3O4 nanoparticles was studied by mu-XRF, magnetic, TEM and SEM techniques. Because of the elevated viscosity of epoxy resin and its effect on particle agglomeration, this study was extended using less viscous polyvinyl alcohol and some sol gels as a matrix. Unlike the results found in epoxy resin, spherical agglomerates were found in a PVA matrix even at Fe3O4 concentration of up to 50%.
