Electric properties of carbon black‐epoxy resin composites at microwave frequencies
Journal of Applied Polymer Science, 1996This present paper is a study of the dielectric behavior of carbon black–epoxy resin composites at the microwave frequencies 9.5 and 35 GHz. The results of this research have shown that the complex propagation constant γg for these mediums depends on the frequency F, on the volume concentration ϕ of the conducting medium, and on the particle size ...

Electric conduction in the polyester resin-acetylene carbon black system
Physica Status Solidi (a), 1976Compositions with a relatively high electrical conductivity and small carbon black concentration are obtained by polymerization of monomers mixture and acetylene carbon black. An considerable influence of polymerization conditions on the electrical conductivity of these compositions are ascertained.

Resistor and dielectric properties of carbon‐black epoxy resin composites
Electronics and Communications in Japan (Part II: Electronics), 1992AbstractIn this paper, the change in carbon black (CB) coherence with CB loading in CB resin composites has been studied from the viewpoint of resistance characteristics (resistivity, temperature coefficient of resistance) and dielectric properties by using HS 500 as CB.

Carbon black (CB) selective dispersion and conductive properties of immiscible thermoplastic/thermosetting polymer blends consisting of polystyrene (PS) and epoxy resin (EP) were investigated in this paper. The results showed that CB particles are preferentially localized in EP phase in PS/EP blends. The blend with 10 pbw (parts by weight) PS presented

ESR and electrical conductivity of carbon black doped polyester resin
Acta Polymerica, 1979AbstractThe dependence between paramagnetic centre concentration, as well as ESR spectral line width and electrical conductivity of a polyester resin doped with various admixtures of acetyelene carbon black has been investigated. Distinct correlations have been found between ESR spectrum and electrical conductivity of the resin as a function of ...

Preparation and Properties of Nanocomposites Consist of Carbon Black N220 and Epoxy Resin
Advanced Materials Research, 2011The nanometer carbon black (CB) N220 of different content was employed to prepare carbon black N220/epoxy resin (CB N220/EP) composites by filling-mixing method. The structure of CB N220 and its dispersion in epoxy resin were analyzed by TEM and tensile fracture surface of the composites was analyzed by SEM. Experimental results showed that CB N220 was
