Alternating electric field induced agglomeration of carbon black filled resins
Polymer, 2002Abstract This letter reports on our observation that an alternating electric field is able to induce the formation of an electrically conducting network in carbon black (CB) filled resins well below the zero-field percolation threshold. Compared with the recently presented dc method, the ac agglomeration is more efficient in two respects: it proceeds

Conduction carriers and localized spin centres in carbon black doped polyester resin
Physica Status Solidi (a), 1980The temperature dependences of ESR spectra of a polyester resin doped with various amounts of acetylene carbon black are investigated. The existence of two types of paramagnetic centres is ascertained i.e. localized paramagnetic centres and paramagnetic conduction carriers.

Integrated optimization of the adsorption of theaflavins from black tea on macroporous resins
2012In this work the adsorption and desorption parameters for the separation of theaflavins from tea are determined. The obtained data is used for a preliminary selection of the resin with the best adsorption capacity and desorption ratio. From the four tested resins the hydrophobic A-DVB resin has the best characteristics.

Correlation between resistor characteristics and cohesive property of carbon black in resin
[1991] Proceedings of the 3rd International Conference on Properties and Applications of Dielectric Materials, 2002Carbon black (CB)-reson composites have been studied through resistivity parameters (resistivity), ( rho ), temperature coefficient of resistance (TCR), a parameter of the dielectric relaxation time, and equivalent circuit parameters (R/sup s/, R/sup c/, C/sup c/) using two kinds of CBs.

Effect of curing temperature on carbon black‐resin thick‐film resistors
Electronics and Communications in Japan (Part II: Electronics), 1991AbstractThe temperature coefficient of resistance (TCR) and the humidity coefficient of resistance (HCR) of carbon black (CB) resin thick‐film resistors are influenced by the properties of the CB and resin.This study showed that the curing temperature changes the cohesive state of CB and influences TCR and HCR of the resistor.

Agglomeration and electrical percolation behavior of carbon black dispersed in epoxy resin
Journal of Applied Polymer Science, 1997In conductive polymer compounds, the filler volume fraction at which a network of touching particles is formed is not a constant but depends on the manufacturing process. By applying three main features—particle-particle interaction, dynamics of agglomeration, and structure of agglomerates—which are well known in colloid science to filled polymers, the
