The dependence of electrical resistivities on the temperature of different polymer systems (including rubbers and plastic/rubber blends) loaded with carbon blacks (including oxidized and normal carbon blacks) were studied. We found that polymer-carbon black interactions could greatly influence the e

β¦ Synopsis
Low-density polyethylene/ethylene-propylene-diene terpolymer/carbon black blends were irradiated in air with a 6oCo y ray or an electron beam accelerator. The absorbed dose ranged from 1-400 Mrad. The influences of irradiation on positive temperature coefficient behavior of the blends were analyzed.

Low-density polyethylene/ ethylene-propylene-diene terpolymer ( LDPE/EPDM) blends and LDPE/ethylene-ethyl acrylate (EEA) blends were chosen as objects of study. Their positive temperature coefficient ( PTC ) phenomena and their distinctive aspects were described. The explanations were given from the
Polyblends prove to be able to provide more possibilities for tailoring conductive polymer composites in comparison with individual polymer systems. Accordingly, ethylene-vinyl acetate-low-density polyethylene (EVA-LDPE) filled with carbon black (CB) was prepared in this study as a candidate for pos
The effects of both dynamic cyclic extension and swelling on the thermoelastic behavior of ethylene propylene diene rubber loaded with different concentrations of carbon black have been studied. As the strain amplitude increases, the concentration of the ruptured bonds increases, leading to more enh
