Nitrogen-doped Graphite-Like Carbon Derived from Phthalonitrile Resin with Controllable Negative Magnetoresistance and Negative Permittivity

Herein, a nitrogen-doped graphite-like carbon material derived from hybrid phthalonitrile (PN) resin with controllable carbon microstructures including crystalline structures, hybridized carbon configurations, degree of disorder, and nitrogen species such as pyridinic N, pyrrolic N, and graphitic N has been manufactured by high-temperature annealing method. By simply altering these carbon microstructures through annealing temperature, the lowest resistivity of 1.76 Ω·cm at 290 K, the negative MR value of − 6.10
