Embodiment 1
[0051] (1) Gas phase pyrolysis method prepares silicon oxide / carbon nanotube composite film material: 1) weigh 24.03g ethanol, 0.432g ferrocene, 0.22g thiophene, wherein, ethanol is as the carbon source of this reaction, ferrocene As a catalyst, thiophene is used as a promoter, and the above-mentioned tetraethyl orthosilicate (TEOS) with a total mass fraction of 4% (~1.028g) is weighed as a silicon source for the reaction, and the above solution is continuously ultrasonically dispersed at 50°C for 60 minutes. After obtaining a relatively uniform dispersion, transfer it to a syringe as a precursor solution; 2) Completely seal the vertical CVD furnace, continuously feed 100 sccm of Ar, completely remove the residual air in the furnace, and raise the temperature of the vertical CVD furnace to 1150°C , keep warm for 5h; 3) After steps 1) and 2) are completed, close the Ar, and continuously inject 800 sccm of H into the furnace 2 , to be H 2 Fill the entire vertical CVD furnace, a...
