摘要： Method for producing an oxidized PAN fiber (OPF) wherein a PAN fiber is subjected to an oxidation process in which reactive oxidizing species are maintained in close enough proximity to the PAN fiber during the oxidation process such that a core of the PAN fiber is converted to a crosslinked thermoset morphology before an oxidized shell of the PAN fiber becomes thick enough to substantially inhibit penetration of the reactive oxidizing species into the core. The resulting OPF possesses a density greater than 1.35 g/cm3 and a substantially homogeneous crosslinked thermoset morphology along a radial dimension of the oxidized PAN fiber. Flame-retarded materials containing the resulting OPF, as well as methods for producing such flame-retarded materials, are also described.
