Carbon Black Reinforced Epoxy Resin Nanocomposites as Bending Sensors
Journal of Composite Materials, 2009By blending electrically conducting carbon black particles and silica into poly(bisphenol A-co-epichlorohydrin) epoxy resin polymer, conductive nanocomposites were prepared by printing onto transparency films and curing. Application of a milling procedure prior to application is beneficial for the reduction of cracks in the subsequent nanocomposites ...

Black Stuff and Babies. Accidental Ingestion of Cannabis Resin
Medicine, Science and the Law, 1988ABSTRACT: Accidental ingestion of cannabis resin by a 2 1/2-year-old girl was followed by 6 to 8 hours of stupor, accompanied by hypothermia and slowing of respiration. She recovered spontaneously with no after-effects. The clinical presentation, sequelae and legal implications of cannabis ingestion by children are discussed.

Percolation in carbon black filled epoxy resin
Macromolecular Symposia, 1996AbstractThe conditions to form a conductive network in carbon black filled epoxy resin were examined. It was found that the formation is controlled by particle‐particle interaction which can be influenced by shear forces or by the ionic concentration of the resin. Therefore the network morphology and thus the percolation threshold depends strongly upon

Epoxy Resin/Carbon Black Composites Below the Percolation Threshold
Journal of Nanoscience and Nanotechnology, 2013A set of epoxy resin composites filled with 0.25-2.0 wt.% of commercially available ENSACO carbon black (CB) of high and low surface area (CBH and CBL respectively) has been produced. The results of broadband dielectric spectroscopy of manufactured CB/epoxy below the percolation threshold in broad temperature (200 K to 450 K) and frequency (20 Hz to 1 ...

Fine dispersion of carbon black in fluorene‐based resin
Polymer Composites, 2008Abstract The dispersion ability of fluorene‐based epoxy resin (FBE), bisphenol A based epoxy resin (PBE), fluorene‐based polyester (FBP), and polycarbonate (PC) in carbon black (CB) was evaluated. CB/FBE composite had a lower L value (reflectance, blackness) than that of CB ...

Field Response of Black Turpentine Beetle to Pine Resin Oxidation and Pheromone Displacement
Journal of Chemical Ecology, 2022The black turpentine beetle, Dendroctonus terebrans, is an economically important pest of pines in the Southeastern U.S., with a high potential for invasion to other pine-rich regions. Dendroctonus terebrans attraction to an injured host tree lessens over time as the host material degrades. Likewise, kairomonal volatiles emitted from the host change as

The Electrical Properties of Epoxy Resin Composites Filled with Cnts and Carbon Black
Journal of Nanoscience and Nanotechnology, 2011This work introduces an experimental activity related to the realization of an epossidic nanostructured material that develops the function of covering for electronic circuits in aeronautical field. This covering meets the demand of protection of these circuits from possible troubles of electromagnetic nature.
