Nano films could include a meaning of functional surface modification for various applications including water wettability control to light absorption/emmision manners. However, in our knowledge , there is few report of investigation of multilayer thin films with spinel ferrite nanoparticles that have microwave absorption properties for stealth function. Taken full advantages of nano-layer fabrication technic, here we prepared spinel ferrite films with polyelectrolytes by Layer-by-Layer (LbL) method and analyzed influences of structures and composition of ferrite nanoparticles incorporated thin films. The composition of ferrite was measured by energy dispersive x-ray (EDS), Crystalline structures were measured by X-ray Diffractometer (XRD) and stealth properties was investigated by calculating permeability and permittivity that obtained from Network Analyzer. |
