Diphenylamine (DPA) was used as an additive to improve the properties of polyethylene (PE)-derived carbon fibers (CFs), resulting in increased char yield, graphitic structure, and melt-spinnability. The PE/DPA-derived CFs exhibited high mechanical strength and modulus.
A small-molecule additive, diphenylamine (DPA), was successfully employed in the production of strong, light, and high-performing polyethylene (PE)-derived carbon fibers (CFs). The incorporated DPA effectively enhanced the char yield, graphitic structure, and melt-spinnability of the PE matrix, as evidenced by various spectroscopic, thermogravimetric, and rheological analyses. Furthermore, the PE/DPA-derived CFs exhibited sound mechanical properties, with a tensile strength of 0.63 +/- 0.13 GPa and modulus of 37.89 +/- 5.53 GPa.
