Abstract :In order to enhance magnetic and thermal properties of polymeric structures in 3D insert ignore into journalissuearticles values(three-dimensional); form, stereolithography technique is an alternative way to in-situ synthesize magnetic nanoparticles such as iron, cobalt and nickel in photocurable resin during laser photopolymerization for magnetic micromachines. By using different types of magnetic nanoparticles in the resin, the formed structure exhibits different mechanical, thermal and magnetic behaviors. In this study, magnetic nanoparticles were synthesized by laser irradiation to investigate the effects of the magnetic nanoparticles in 3D structure. Under constant metal salt amount and forming layer thickness, morphological, characterization, mechanical, thermal and magnetic properties were conducted by scanning electron microscope insert ignore into journalissuearticles values(SEM);, transmission electron microscope insert ignore into journalissuearticles values(TEM);, tensile test, thermal gravimetric analysis insert ignore into journalissuearticles values(TGA);, differential scanning calorimetry insert ignore into journalissuearticles values(DSC); and vibrating sample magnetometer insert ignore into journalissuearticles values(VSM);, respectively. As a result, it observed that the magnetic properties of iron-based polymeric structures show higher saturation magnetization insert ignore into journalissuearticles values(0.0145 emu/gr); while thermal stability remains low for other magnetic embedded polymer samples. In the presence of magnetic nanoparticles, its mechanical strength decreased from 14 MPa to 5 MPa for all experiments against pure 3D resin, as well as it leads to more fragile structures. Finally, for each sample, singular magnetic nanoparticles were formed in the polymer matrix and verified that nanoparticles are completely reduced.
