Morphology of Polyethylene–Carbon Black Composites
Carbon black is a common polymer additive that is used for reinforcement and for its ability to enhance physical properties, such as conductivity. This article pertains to an X-ray scattering (SAXS) study of a conductive grade of carbon black and carbon black–polymer composites. The scattering pattern for such blacks displays a surface-fractal-like power-law decay over many decades in scatterin...
متن کاملThe downshift of the electrical percolation threshold in polyisoprene-nanostructured carbon composites
Riga Technical University, Institute of Technical Physics, Azenes Str. 14-322, LV-1007 Riga, Latvia E-mail: [email protected] In our previous research, the polyisoprene-nanostructured carbon composite (PNCC) has been approved as a promising material to be used as a low-pressure sensor. The main advantage of PNCC is its hyperelastic flexibility as compared with conventional piezo-ceramic pr...
متن کاملElectrical permittivity and conductivity of carbon black-polyvinyl chloride composites
Electrical conductivity and permittivity of carbon black-polyvinyl chloride composites were studied over a wide frequency spectrum (dc, 1.3 GHz). Conductivity of the bulk composites increases with higher volume fraction of carbon black as expected. However, the functional dependence of the increasing conductivity with carbon black loading is different below and above the percolation threshold b...
متن کاملElectrical Conduction in Nonlinear Composites
Composite systems constitute a large class of naturally occurring or artificially synthesized disordered systems [1]. The systems are microscopically inhomogeneous and disordered but look homogeneous on the macroscopic scale. From the tunnelling electron micrographs (TEM) of such a composite material it can be seen that the typical dimension (ξ) of metallic islands embedded in the insulating ma...
متن کاملElectrical Conduction Behavior of Cement-Matrix Composites
As structural materials, cement-matrix composites have received much attention in terms of their mechanical properties, but relatively little attention in terms of their electrical conduction properties. Nevertheless, the electrical properties are relevant to the use of the structural materials for non-structural purposes such as sensing and electromagnetic interference (EMI) shielding. The abi...
