Abstract
Transmission electron microscopy and scanning electron microscopy were used to investigate chemically cycled magnetite-based composites using mesoporo us sulfonated styrene-divinylbenzene copolymer as template, The micron-size d morphology of the template was investigated using scanning electron micro scopy, while transmission electron microscopy provided useful information c oncerning the nanoparticle size polydispersity profile and location of the magnetite nanoparticles inside the template. The narrowing of the nanoparti cle size distribution and the linear dependence of the magnetite mass incor poration versus number of chemical cycles are supported by the transmission electron microscopy data.
