摘 要:Magnetic ultrathin films were fabricated layer-by-layer using a self-assembly method through the electrostatic interaction between the photosensitive diazoresin (DR) and the negatively charged Fe 3O 4 nanoparticles (NP-Fe 3O 4).The results of the UV-vis spectra and AFM show that the assembly of DR and NP-Fe 3O 4 is very *** UV irradiation,the ionic bonds of the DR/NP-Fe 3O 4 film convert to covalent ones and the magnetic films become very stable toward polar *** magnetic film images with good resolution are obtained by means of selective UV-exposure of the film under a photo-mask and then developing the exposed film in the saturated aqueous solution of sodium dodecyl sulfate (SDS) and cetyl trimethyl ammonium bromide (CTAB),respectively.
