The aims of the present work are: (i) the synthesis of several
samples of magnetite nanoparticles, with tuned sizes, using the
Massart method at different initial conditions, followed by the
synthesis of cellulose–magnetite beads; (ii) the characterization of
the samples by means of several solid state techniques and the
analysis of the effect of varying iron concentration and temperature
in the mean size of magnetite nanoparticles; (iii) the study of
the internal morphological structure and magnetic properties of
the composite material via electron microscopy.
