Usability of natural titanium-iron oxide as filler material for ionizing electromagnetic radiation shielding composites; preparation, characterization and performance

摘要

In the study, usability of natural titanium-iron oxide filler for ionizing electromagnetic radiation (IEMR) shielding composites with isophthalic polyester (PES) matrix was investigated for the first time. Shielding performances of the composites were also investigated for three different IEMR energy regions as low, intermediate and high for the first time, too. Mass attenuation coefficient of prepared composite with the best shielding performance reached 80 % of elemental lead's performance at low energy regions while it had higher mass attenuation coefficient at intermediate and high energies.
