Abstract

This work examines the preparation of polymer nanocomposites using strontium ferrite nanoparticles and their analysis using VSM, TGA, XRD and SEM methods. First, strontium ferrite nanoparticles were prepared by appropriate synthetic methods. Then these nanoparticles were used as a filler in the polymer matrix to prepare nanocomposites. Then, using VSM, the magnetic properties of nanocomposites were investigated. This method measures and studies the magnetic properties of the samples, including magnetization, hysteresis, and continuous and quasi-continuous magnetizations. Also, using TGA, weight changes of nanocomposites were evaluated as soon as the temperature changed. This method was used to check the thermography of the samples and determine their thermal stability and thermal decomposition. Also, using XRD, the crystal structure of nanocomposites was investigated. This method helped to identify the phases and crystal structure of the samples. Finally, by using SEM, the surface and morphology of nanocomposites were examined by imaging equipped with irradiated electrons. This method detected the size and distribution of particles in the samples and examined their surface structure. As a result, this work deals with the investigation and better understanding of polymer nanocomposites with high thermal properties and high flammability by using the methods of preparing strontium ferrite nanoparticles, preparing nanocomposite and using VSM, TGA, XRD and SEM analyses. These findings can be used in various industries, including polymer, electronics, energy, automotive and aerospace industries
