High surface area and low structure carbon blacks for energy storage applications

Abstract: The present invention, in part, relates to a carbon black having a) a nitrogen BET surface area (BET) of from about 600 m 2 /g to about 2100 m 2 /g, b) a CDBP value in mL/100 g of from about (−2.8+(b*BET)) to about (108+(b*BET)), where b is 0.087 and BET is expressed in m2/g, and c) an apparent density (p, g/cm 3 ) of at least about 0.820+q*BET, where q=−2.5×10 −4 , as determined at a compressive force (P) of 200 kgf/cm 2 on dry carbon black powder. Energy storage devices, such as electrochemical double layer capacitors (EDLC's), containing the carbon black are also disclosed. Methods for making the carbon blacks and EDLC's made with them are also provided.

Modified fillers and elastomeric composites comprising same

Abstract: Modified fillers are described which have adsorbed and/or attached chemical groups, such as a triazole and/or pyrazole thereon. Other modified fillers are also described. Elastomeric compositions containing the modified filler are further described, as well as methods to improve hysteresis and/or abrasion resistance in elastomeric compositions using the modified fillers of the present invention.

Ink compositions comprising salts with polyvalent ions

Abstract: An ink composition and, in particular, an ink composition, comprising a liquid vehicle, at least one modified pigment having attached at least one functional group, at least one salt having a polyvalent ion, and at least one polymer is disclosed Methods of generating an image using this ink composition are also described

High resistivity compositions

Abstract: The present invention relates to a black matrix formed by applying a curable coating composition onto a substrate to form a curable coating, curing the curable coating imagewise to form a coating, and developing and drying the coating. The curable coating composition comprises a vehicle, a curable resin, and at least one modified pigment comprising a pigment having attached at least one organic group having the formula -X-I or -X-NI, wherein X, which is directly attached to the pigment, represents an arylene or heteroarylene group, an alkylene group, an aralkylene group, or an alkarylene group, I represents a non-polymeric group comprising at least one ionic group or at least one ionizable group, and NI represents a non-polymeric group comprising at least one nonionic group. The curable coating composition, curable coating, and cured coating are also described. Also disclosed is a method of controlling the resistivity of a coating.

Silicone rubber compositions incorporating silicon-treated carbon blacks

Abstract: Silicone rubber compositions are disclosed including a silicone polymer and a silicon-treated carbon black. The silicon-treated carbon blacks include a silicon-containing compound that is distributed through at least a portion of the carbon black aggegrate. The silicon-treated carbon black is incorporated within a silicone rubber composition as an alternative reinforcing and extending filler, imparting higher hardness to elastomers formed from the composition, when compared to silicone rubber compositions incorporating an untreated carbon black.
