چکیده انگلیسی
This work explores the fabrication of free-floating magnetic structures on a photocurable nanocomposite consisting of superparamagnetic magnetite nanoparticles (Fe3O4) and a commercial SU-8 negative tone photoresist. The nanocomposite was synthesized by mixing magnetic nanoparticles with different kinds of SU-8 resin. We demonstrated that the dispersion of Fe3O4 nanoparticles in nanocomposite solution strongly depended on the particles concentration, the viscosity of SU-8 polymer, and the mixing time. The influence of these factors was demonstrated by examining the structures fabricated by mask photolithography technique. We obtained the best quality of structures at a low concentration, below 5 wt%, of Fe3O4 nanoparticles in SU-8 2005 photoresist for a mixing time of about 20 days. The manipulation of free-floating magnetic microstructures by an external magnetic field was also demonstrated showing promising applications of this magnetic nanocomposite.
