| Abstract | ||
| In this research, a polymeric composite material with a polystyrene basis reinforced with iron sulfate (FeSO4) nanoparticles was manufactured at a percentage of (5, 10, 15, 20 and 25)%. The manufactured samples were subjected to specific temperatures (T=40, 60 and 80) C° and for specific periods of time (3, 6, 9) hours. The samples were subjected to surface hardness and impact strength tests, to identify their ability to endure the thermophysical effect. These values differed with the difference in the temperature of the sample treatment and also with the period of the exposure of the samples to the thermophysical effect. Results showed that an increase in the values of surface hardness when adding FeSO4 nanomaterial to the polystyrene with a concentration of 20% and temperature of 80Cº and impact strength recorded the highest value when adding nanomaterial at 20% when exposed to a temperature 40C° for 3 hours according to the control treatment, while those values began to decrease when the percentage of FeSO4 nanomaterial was increased to 25%. Results of X-ray diffraction spectrum and Scanning Electron Microscope images showed the beginning of decomposition of polystyrene reinforced with FeSO4 nanoparticles with a concentration of 20% under a temperature of 60Cº. | ||
