preparation example Construction
[0040] The present invention also provides a kind of preparation method of above-mentioned superhydrophilic agent simultaneously, it is characterized in that, comprises the steps:
[0041] Step 10: preparing zinc oxide nanorods;
[0042] Step 20: dissolving 0.1-0.45wt% zinc oxide nanorods into 12-18wt% N,N-dimethylformamide to prepare zinc oxide sol;
[0043] Step 30: Mix a dispersant with a volume ratio of 5-8:1 and a strong acid solution to form a dispersion, then add 1.5-5 wt% carbon nanotube powder to make the pH of the solution 2-4, and then Stir at 30°C for 1 to 3 hours, and mix evenly to obtain a carbon nanotube dispersion;
[0044] Step 40: Gradually add the carbon nanotube dispersion prepared in Step 30 to the zinc oxide sol prepared in Step 20 under continuous stirring, and then age for 10-24 hours to form a superhydrophilic agent. Wherein, wt% is weight percentage, h is hour, and the weight percentage of each component mentioned above refers to its weight ratio th...

[0056] Embodiment 1: the preparation method of superhydrophilic agent
[0057] (1) Preparation of nano-zinc oxide: 1g of zinc acetate dihydrate (Zn(OAc) 2 2H 2 O) and 0.1g triamine citrate ((NH 4 ) 3 C 6 h 5 o 7 ) into 120ml of absolute ethanol, condensed and refluxed at a temperature of 90°C and stirred continuously to dissolve it, and the prepared solution was cooled and stored in a refrigerator at a temperature of 3°C to obtain a precursor solution; 0.1g of sodium hydroxide (NaOH) was added to 30ml of absolute ethanol, ultrasonically dissolved at room temperature for a period of 40min (minutes), and then the prepared 20ml of sodium hydroxide ethanol solution was added to the prepared 60ml of the precursor solution, in a water bath with a temperature of 70°C Continue to react in the environment for a period of 4 hours (hours), after ultrasonication, centrifugation, and washing for 3 to 5 times, dry at room temperature to prepare zinc oxide nanorods.
