09.01.: Invited Seminar Talk: Dr. Anna Gulyakova, Relaxation processes determining the electret stability of high-impact polystyrene/titanium-dioxide composite films

In the talk, the influence of relaxation processes on the thermal electret stability of high-impact polystyrene (HIPS) free-standing films filled with titanium dioxide (TiO2) of the rutile modification are described and discussed. Films with 2, 4, 6 and 8 vol.% TiO2 are compared to each other and to non-filled samples. The samples were investigated by means of a combination of electrical/dielectric methods supplemented with differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA).
