Widespread use of polymeric materials from the items for daily use to electrical engineering, electronics and medical applications causes a need for their detailed examination under various external influences. Dielectric spectroscopy allows monitoring changes in the structure of polymers under various external influences. In this paper we analyzed β relaxation recorded in polymer woven structures and meshes based on polyethyleneterephtalate. Based on the results obtained, a comparative analysis of dielectric parameters and structural characteristics of the samples was done.
