Highly conductive graphite

The first-generation APU hardware for MEAs with 100 cm in the active area has been based on high-conductivity graphite plates. The maximum power generated by a single APU cell has been 21 W at a total cathode pressure of 2.8 atm and air stoichiometry of 2.1 (Figure 5). The same cell has...

Substituted derivatives, copolymers, and blends show better thermal stability. Highly conductive graphite films have been prepared by pyrolysis of poly(phenylenevinylene) (>3000°C), stretched samples doped with SO3 had conductivities of 10 S/cm [20]. Poly(phenylenevinylene) can be used as tunable polymer diodes or luminescent electrodes [83]. 

For some applications, such as trays of conveyer belts for electronic components, copiers and printers, or even artificial turf, more permanent antistats are desired. One approach is the use of polymers such as polyether amide copolymers or ethylene ionomers. Highly conductive graphite and metal fibers such as nickel fiber are also used to lower the resistivity of polymer articles [15]. For high performance materials that can tolerate the added cost impact, carbon nanotubes can also be used. 

Natural graphite is required in some motor and generator bmshes. Its high conductivity, high contact drop, and anisotropy make it particularly usehil in bmshes for d-c equipment. 

Alternative explanations of the high conductivity of composite materials obtained by polymerization filling are given in works [62, 63] where conductivity higher than that of the graphite proper is attributed to a polymer interlayer between graphite particles, are, in our opinion, insufficiently convincing and cannot explain the whole of the experimental data. 

Although the covalent compounds of graphite are thus important in their own right, they represent the extreme form of oxidative intercalation. The use of fluoride compounds to achieve highly conductive materials may ultimately lead to new forms of graphite fluoride SI).
