Abstract
This work focuses on the absorption characteristics of polyimides with different molecular rigidity in the temperature range of 25–175 °C. The temperature dependences of conductivity were obtained, the absorption coefficients, dielectric characteristics ɛ’(ω), ɛ’’(ω) in the range of 10-1–10-3 Hz were calculated. Experimental data suggest that charge accumulation in the films is caused by Maxwell-Wagner polarization. The dependency between the polyimide rigidity and electrical and dielectric characteristics was not found.
