The study is devoted to investigating the possibility of using an alternating magnetic field (AMF) for deposition and covering a stent
surface and improve its functionalities with a new magnetic composite (MC). MC was prepared in situ during functionalization
of poly(maleic anhydride-co-3,9-divinyl-2,4,8,10-tetraoxaspiro [5.5] undecane) copolymer by opening the anhydride ring with
erythritol and introducing magnetic nanoparticles into the polymer matrix. Ten different solvents were used to evidence the
dependence between AMF presence, the reaction medium characteristics and the kinetic deposition. Interdependence among the
viscosity, density and molar polarization of the solvents and the yield of deposition was registered. The covering of stent with MC is
also analyzed by microscopy and the new magnetization values are estimated.
