Abstract
Electrically conductive carbon compositions are disclosed which are formed from carbon having a graphite-like structure and a nitrosyl or nitronium salt or salts. The nitrosyl or nitronium salt reacts with the carbon to intercalate it with charge-exchange atoms or molecules. Binary, ternary and multi-intercalated lamellar compositions are produced according to the particular reaction process selected. The compositions may be used alone as electrical conductors or may be combined in a matrix to form composite conductors.
Claims31
An electrically conductive lamellar carbon composition, which comprises:
- carbon having a graphite-like, stacked-plane-crystalline form intercalated with one or more nitrosyl salts selected from NOX or nitronium salts selected from NO.sub.2 X wherein X is a stable, conjugate anion of an electrophilic atom, molecule or Lewis acid, said anion being selected from the group consisting of a halide anion, oxyhalide anion, bisulfate anion, nitrate anion, boron halide anion, a stable halide anion of a first, second or third transition series metal, a halide anion of a group IVa metaloid and a halide anion of a group Va metaloid;
- and wherein the proportion of the nitrosyl salt or salts or nitronium salt or salts to carbon in the composition produces a resistivity of the composition of less than about 10.sup.-5 ohm cm.
