The development of multifunctional and high-performance fibers has received much attention owing to a broad application prospect. In this work, the synergistic effect of ionic liquid modification on dispersion of graphene and carbon nanotubes in polyamide 6(PA6) was studied, and the composite fiber was prepared using melt spinning after a simple pre-solution blending. Imidazole chloride ionic liquid is adsorbed on the surface of the two carbon nanofillers through non-covalent bond, which gives a good dispersion and interface bonding in PA6 matrix. When the mass ratio of functionalized carbon nanofillers is 1:2, the mechanical properties and thermal stability of PA6 composite fiber are significantly improved compared with the pure PA6 fiber. Moreover, the PA6 composite fiber has a UV protection factor (UPF) of 158.2 and good antistatic performance with a surface resistivity of 2.60 × 107 Ω · cm. In addition, there is an excellent photothermal conversion performance from the results of 200 W infrared light irradiation test and outdoor photothermal experiments. This work provides a new idea to prepare multifunctional and high-performance composite fibers. [ABSTRACT FROM AUTHOR] |
