Four different grades of pitch-based graphite fibers (Amoco P-55, P-75, P-100, and P-120) were intercalated with each of four different intercalates: bromide (Br,), iodine monochloride (ICI), copper(I1) chloride (CuCI,), and nickel(H) chloride (Nit&). The P-55 fibers did not react with Br? or Nit&,
A differential scanning calorimetric survey of brominated PAN, pitch-based and vapor-grown fibers revealed that only vapor-grown fibers heat-treated to temperatures of 2250ยฐC or above exhibited the phase change at 1OOT associated with the two-dimensional melting of bromine, similar to that observed
series of high performance, experimental carbon/graphite fibers was intercalated and examined with respect to their metallic conductivity behavior by resistivity and magnetoresistance versus temperature measurements. One fiber was a polyacrylonitrile (PAN&type precursor and three were pitch base pr
