Embodiment 1
[0027] (1) Preparation of composite fiber: Add 26.3 mg of ammonium tetrathiomolybdate to 2.0 mL of PEDOT:PSS solution with a concentration of 10.5 mg / L, shake vigorously until the solution gels, and inject the gelled mixture into Put it into a polytetrafluoroethylene capillary tube, heat it with water at 180.0°C for 10.0h, cool to room temperature, and take out PEDOT:PSS / MoS 2 Gel fiber, soaked in concentrated sulfuric acid for 12.0h to remove most of the PSS, to obtain PEDOT / MoS 2 Composite fibers. (2) Washing: the PEDOT / MoS obtained in step (2) 2 The composite fiber is directly washed with deionized water; (3) drying: fix both ends of the washed fiber and dry at 60.0°C for 2.0h;
[0028] For a kind of PEDOT / MoS prepared above 2 The composite fiber was tested for microscopic morphology, structure and electrochemical performance, and the following results were obtained: figure 1 The low-magnification scanning electron micrographs shown, such as figure 2 The high-magnific...
Embodiment 2
[0030] (1) Preparation of composite fiber: Add 13.15 mg of ammonium tetrathiomolybdate to 2 mL of PEDOT:PSS solution with a concentration of 7.5 mg / L, shake vigorously until the solution gels, and inject the gelled mixture into In a PTFE capillary, heat at 200.0°C for 8.0 hours, cool to room temperature, and take out PEDOT:PSS / MoS 2 Gel fiber, soaked in concentrated sulfuric acid for 15.0h to remove most of the PSS, to obtain PEDOT / MoS 2 Composite fibers. (2) Washing: the PEDOT / MoS obtained in step (2) 2 The composite fiber is directly washed with deionized water; (3) drying: fix both ends of the washed fiber and dry at 70.0°C for 1.5h;
[0031] For a kind of PEDOT / MoS prepared above 2 The composite fiber was tested for microscopic morphology, structure and electrochemical performance, and the following results were obtained: image 3 The low-magnification scanning electron micrographs shown, such as Figure 4 The high-magnification scanning electron micrographs shown are...
Embodiment 3
[0033] (1) Preparation of composite fibers: Add 104.0 mg of ammonium tetrathiomolybdate to 4.0 mL of PEDOT:PSS solution with a concentration of 15.0 mg / L, shake vigorously until the solution gels, and inject the gelled mixture into Put it into a polytetrafluoroethylene capillary tube, heat it with water at 140.0°C for 24.0h, cool to room temperature, and take out PEDOT:PSS / MoS 2 Gel fibers were soaked in ethylene glycol for 30.0h to remove most of the PSS to obtain PEDOT / MoS 2 Composite fibers. (2) Washing: the PEDOT / MoS obtained in step (2) 2 The composite fiber is directly washed with deionized water; (3) drying: fix both ends of the washed fiber and dry at 70.0°C for 1.5h;
[0034]For a kind of PEDOT / MoS prepared above 2 Composite fibers were tested for microscopic morphology, structure and performance, and obtained similar image 3 The low magnification scanning electron micrographs shown are similar to Figure 4 The high-magnification scanning electron micrographs sh...
