specific Embodiment approach 1
[0015] Embodiment 1: The MXene-polyaniline composite material of this embodiment is composed of a layered two-dimensional transition metal carbide and a polyaniline shell coated on the surface of the two-dimensional transition metal carbide, wherein the two-dimensional transition metal carbide The ratio of the mass of polyaniline or carbonitride to the mass of polyaniline is 1: (0.5-2.5).
specific Embodiment approach 2
[0016] Specific embodiment two: the preparation method of the MXene-polyaniline composite material described in specific embodiment one, carry out according to the following steps:
[0017] 1. Weigh two-dimensional transition metal carbide (MXene), aniline and ammonium persulfate [(NH 4 ) 2 S 2 o 8 ], wherein the ratio of the quality of two-dimensional transition metal carbide to the volume of aniline is 1g:(0.3~3)mL, the ratio of the quality of ammonium persulfate to the volume of aniline is (2.5~2.75)g:1ml;
[0018] 2. Add aniline to water, stir to obtain aniline / water dispersion, then use hydrochloric acid to adjust the pH value of the aniline / water dispersion to 1.5-2 to obtain aniline hydrochloride solution;
[0019] 3. Add the hydrochloride solution of aniline to the aqueous dispersion of the two-dimensional transition metal carbide, stir and mix at 0-5°C for 6-18 hours to obtain the MXene / aniline mixed solution;
[0020] 4. Dissolve ammonium persulfate in water, adj...
specific Embodiment approach 3
[0021] Specific embodiment three: the difference between this embodiment and specific embodiment two is that the two-dimensional transition metal carbide described in step one is Ti 3 C 2 ; Others are the same as in the second embodiment.
