The Department of Functional Materials was established in February 2021. It focuses on functional materials in the context of their specific mechanical, thermal and electrical properties and recognizing them as future-proof materials with the prospect of many new applications.
The research work of the Department includes the design, production, analysis of the properties, structure and degradation processes of functional materials. A significant part of the research relates to composites, gradient materials as well as nanomaterials. The research conducted by the employees of the Department is of a utilitarian and interdisciplinary nature, binding not only scientific issues in the field of materials science, but also chemistry, physics and mechanical engineering. A great advantage of the Department is the use of a wide range of advanced research methods, such as: dielectric spectroscopy, electron microscopy, atomic force microscopy, acoustic emission studies and a number of calorimetric methods.
Most of the research work is carried out in cooperation with Polish and foreign research centers: Universite de Bordeaux, Technische Universitat Dresden, Medical University of Warsaw, Universidade do Minho, Universidade de Aveiro.
