摘要： A conductive composition is obtained by dispersing conductive particles in a curable polymer. At least 50% by weight of the entire conductive particles are those conductive particles coated with a metal on their outermost layer surface and having a specific gravity which differs within ±1.5 from the specific gravity of the curable polymer. The composition remains stable during storage, experiences a minimal change with time of curability, and cures into a conductive rubber which experiences a minimal change with time of volume resistivity.

Preferably, carbon nanotubes may be present in the range of about 0.5-20% by weight of the composite. The composites are prepared by mixing or dispersing carbon nanotubes in polymer emulsion using an energy source such as a Waring blender. The liquid in the mixture is then evaporated to obtain the composite comprising the polymer and the nanotubes.

摘要： Carbon fiber-filled PC-ABS resin compositions which have improved electrical properties at a given level of carbon fibers, and which do not suffer from as significant a decrease in impact strength as would result from the introduction of generic carbon fibers are achieved using carbon fibers treated with a polyamide terpolymer binder. The bundles are dispersed within the PC-ABS blend. The compositions can be used for injection molding of articles for use as components in applications requiring static dissipation and/or EMI shielding. Such articles include, but are not limited to electronic devices, dust handling equipment and notebook computer enclosures.

摘要： The invention provides a melt-processable conductive fluorothermoplastic composition comprising three components. The first component is at least one melt-processable, thermoplastic fluoropolymer component having its interpolymerized units derived from (i) at least 50 wt % of TFE, and (ii) one or more ethylenically-unsaturated monomers represented by the formulas (a) CF2═CF—Rf, (b) CF2═CF—O—Rf′, and (c) CH2═CR2, wherein Rf is a perfluoroalkyl of 1 to 8 carbon atoms, Rf′ is Rf or a perfluoroalkoxy of 1 to 8 carbon atoms, and R is selected from H, F, Cl, or an aliphatic group having from 1 to 8 carbon atoms which may have F or Cl substituents. The thermoplastic fluoropolymer component is substantially free of interpolymerized units derived from VDF. The second component is from about 0.1 to about 10 weight percent of a hydrocarbon polymer, and the third component is from about 1 to about 20 weight percent of conductive filler. The invention also provides a method for making fluorothermoplastic compositions and shaped articles comprising a conductive fluorothermoplastic composition.
