AC Conduction Mechanism in (Cu)x/(CuTl)-1223 Nanoparticles–Superconductor Composites

The glass composition 40 Li 2 O –5 WO 3–(55−x) B 2 O 3: x V 2 O 5 for x = 0.2, 0.4, 0.6 and 0.8 is chosen for the present study. The glass samples were synthesized by conventional melt-quenching technique. The dielectric properties such as constant (ε′), loss (tan δ) and ac conductivity (σac) are carried out as a function of temperature (30–270°C) and frequency (102–105 Hz). The glass sample (at x = 0.6) exhibited highest ac conductivity (σac) and spreading factor (β) among all the samples. All glasses exhibited mixed conduction (both electronic and ionic) at high temperatures. The frequency exponent s denotes the ac conduction mechanism is associated with both QMT model (at low temperatures) and CBH model (at high temperatures).

Carbon black was first activated by grafting and coupling respectively. Then the grafted carbon black, coupled carbon black, together with the unmodified carbon black was filled into polypropylene to prepare three kinds of composites respectively. The measurements of Fourier Transform Infrared Spectroscopy (FTIR) and alternating current (AC) electrical properties were performed on the composites. And the effect of CB activation on the AC electrical properties was analyzed. Seen from the result of FTIR spectra it can be found that different groups are bonded to the surface of carbon black after activation. For the corresponding conductive composites,it was found that the value of percolation threshold decreases and the electrical conductivity improves consequently after the carbon black activation. The influence of carbon black activation on the AC electrical properties of the composites and their variation with frequency was analyzed. The AC conduction mechanism was discussed and the conduction model was constructed based on the analysis.
