Study of the Process of Synthesis of Functional Fillers for Polymer Composites for Protection against Electromagnetic Radiation

Article Preview

Abstract:

Currently, great attention is paid to the creation of polymer composites using functional fillers and polymer matrices of various types, including thermoplastic and thermosetting types. These fillers also make it possible to increase the protective properties of the polymer against electromagnetic radiation by several orders of magnitude. The aim of the study is to study of the process of synthesis of functional fillers for polymer composites for protection against electromagnetic radiation. As a result of the studies conducted, the process of synthesizing functional fillers for polymer composites for electromagnetic radiation protection has been comprehensively examined. It has been shown that the recrystallization of titanium oxide from solution-melts of KCl-NaCl and KCl-NaCl-∑TiClₙ is possible under a flow of inert gas in the presence of a reducing agent, resulting in thread-like crystals of fibrous form. In the process, thread-like rutile crystals with cross-sectional dimensions of 3–30 μm and lengths of 10³–10⁴ microm were obtained. It has also been established that blowing KCl-NaCl-TiCl₄ without TiO₂ with inert gas in the absence of a reducing agent results in the crystallization of metallic titanium in the form of hollow microspheres. The obtained functional fillers have great potential in the development of polymer composite materials for electromagnetic radiation protection, providing a high combination of strength and spectral characteristics.
