| Sumario: | The distinctive mechanical and photothermal properties of Molybdenum sulfide (MoS<sub>2</sub>) have the potential for improving the functionality and utilization of silk products in various sectors. This paper reports on the preparation of regenerated silk fibroin/molybdenum disulfide (RSF/MoS<sub>2</sub>) nanoparticles hybrid fiber with different MoS<sub>2</sub> nanoparticles contents by wet spinning. The simulated sunlight test indicated that the temperature of 2 wt% RSF/MoS<sub>2</sub> nanoparticles hybrid fibers could rise from 20.0 °C to 81.0 °C in 1 min and 98.6 °C in 10 min, exhibiting good thermal stability. It was also demonstrated that fabrics made by manual blending portrayed excellent photothermal properties. The addition of MoS<sub>2</sub> nanoparticles could improve the toughness of hybrid fibers, which may be since the mixing of MoS<sub>2</sub> nanoparticles hindered the self-assembly of β-sheets in RSF solution in a concentration-dependent manner because RSF/MoS<sub>2</sub> nanoparticles hybrid fibers showed a lower β-sheet content, crystallinity, and smaller crystallite size. This study describes a new way of producing high toughness and photothermal properties fibers for multifunctional fibers’ applications. |
