Abstract
The experimental results of the research of thermoelectrets on the basis of the filled and plasticized poly (vinylchloride) (PVC) are presented. It is proved, that the thermoelectret effect and properties of these composites can be purposely regulated by the type and concentration of the fillers, plasticizer, by intensity of the outer electric field in a certain polymeric matrix. As the result, it enables to get composites with the improved electret’s characteristics.
