Embodiment 1
[0040] Weigh 1.008g deionized water, 0.072g GR high-purity absolute ethanol, 0.0036g titanium tetrachloride, and 0.02g pure carbon tube film. Among them, titanium tetrachloride is used as the titanium source of this reaction, the carbon tube film is used as the carbon source, and absolute ethanol is used for the alcoholysis.
[0041] A method for preparing titanium dioxide-carbon nanotube flexible composite film, comprising the following steps:
[0042] (1) Add GR high-purity absolute ethanol to a dry beaker, add carbon tube film, and start magnetic stirring; add titanium tetrachloride solution drop by drop, and continue stirring for 10 minutes after the drop;
[0043] (2) After the solution is transparent, first use clean tweezers to transfer the carbon tube film to a beaker filled with deionized water, turn on magnetic stirring, and transfer the solution to a beaker filled with deionized water, the transfer method is drop by drop Add, dropwise time is 30min; After the solut...
