specific Embodiment approach 1
[0027] Embodiment 1: The method for assisted brazing of dissimilar materials in the carbon nanotube sponge intermediate layer of the present embodiment is carried out according to the following steps:
[0028] Step 1: Mix the carbon nanotube powder with a strong acid solution, and then perform ultrasonic cleaning at a constant temperature of 60°C to obtain a suspension;
[0029] Step 2, dispersing the suspension obtained in step 1 into deionized water to obtain a mixed solution, then vacuum filtration of the mixed solution to obtain a filter cake, then continue to wash the filter cake, and finally peel off the filter cake and the filter membrane;
[0030] Step 3, ultrasonically dispersing the filter cake obtained by stripping in step 2 into absolute ethanol, centrifuging, and retaining the supernatant;
[0031] Step 4, carry out vacuum filtration on the supernatant obtained in step 3, peel off to obtain a filter cake, and finally dry to obtain carbon nanotube sponge;
[0032]...
specific Embodiment approach 2
[0042] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the carbon nanotube powder in step 1 is single-wall carbon nanotube, double-wall carbon nanotube or multi-wall carbon nanotube.
specific Embodiment approach 3
[0043]Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the ratio of the mass of the carbon nanotube powder described in step 1 to the volume of the strong acid solution is (10-200) mg: (10-30) mL .
