Paramagnetic influence of the addition of Ni0,5Zn0,5Fe2O4 nanoparticle in the structural and dielectric properties of natural rubber films: preparation and characterization

Abstract

This work is about incorporation of paramagnetic nanoparticles (Ni0,5Zn0,5Fe2O4), obtained by polio method, in films of natural rubber for application in absorption microwave. The composites will be prepared by mixture of latex of natural rubber (clone Hevea Brasiliensis -RRIM 600), with the nanoparticles in different proportions using method of casting in different temperature, obtained NR/FZN composites. The characterization studies will be made by spectroscopy in the ultra-violet (UV-vis), spectroscopy for infra red (FT-IR) and micro Raman, thermal analyses (DSC, TG and DMA), connected thermogravimetry together with infra red (TG/FT-IR), measures of electric conductivity in the volume and impedance spectroscopy. The growth kinetics and the production of the thin films still to be explored in the production of pressure sensor.
