In this work space charge accumulation characteristics of nanostructured PP-SiO2 films are investigated, providing preliminary results at the basis of the new materials formulations developed in the European project GRIDABLE, where novel MV and LV DC capacitor films having enhanced performance with respect to present polypropylene films are being developed. This paper shows that nanostructuration may be beneficial, especially at higher temperature, to improve material performance. Better space charge performance will help in optimizing the dielectric strength, design field and reliability of the insulation system for DC use.
