Abstract
The article presents the data of electret-thermal analysis of ultrahigh molecular weight polyethylene as a polymer material promising for medicine and technology, polyvinyl alcohol as a biocompatible gel-forming polymer, blood as a system with coordinatively bound polarizable components, synovial fluid as a component of the lubricating medium of joints containing giauloronates and cholesterol esters, starch-containing polymer biodegradable compositions, chitosan as a natural electret biopolymer, vegetable oils as systems with supramolecular formations in the form of fatty acid triglyceride associates. The variants of interpretation of the thermally stimulated current spectra obtained during the analysis are proposed, which are based on the fundamental concepts of dielectric physics, condensed matter physics, and related natural science disciplines. It is concluded that the addition of the content of curricula in individual academic disciplines with information about this method will contribute to improving the effectiveness of specialists training by institutions of higher education.
