Figure A3

The dispersion of Fe3O4 nanoparticles in SU-8 2000.5, SU-8 2002, and SU-8 2005. (a) images of three bottles of nanocomposites solutions, taken just after mixing; (b) after a few hours, the sedimentation occurred in the nanocomposite solution having a low viscosity of 2.49 cSt and 7.5 cSt; zoom in image of the bottle containing the Fe3O4/SU-8 2005 nanocomposite, after (c) one day and (d) 20 days of the preparation.
