【 摘 要 】

The work is devoted to the investigation of relaxation processes in composite films of polypropylene with aerosil. The investigation shows that relaxation of electret state is determined by the bulk conductivity. Two volume percentage of aerosil is optimal volume for electret stability of samples. The investigation of the sample by means of the method of thermostimulated depolarization reveals that particles of aerosil in composite samples play the role of macrodipoles.
