Problems solved by technology

In particular, organic polymers are often introduced during the synthesis process, and their interaction with surfactants may be more effective in regulating the microstructure of the film surface. However, there have been no reports on the use of surfactants to regulate the surface microstructure of titanium dioxide films.

Embodiment 3

[0036] According to the method for synthesizing super-hydrophilic film using titanium dioxide modified with surfactants, the titanium dioxide sol is prepared by dropping 2 mL of secondary water into 6 mL of tetrabutyl titanate and 24 mL of anhydrous at room temperature and under vigorous stirring conditions. In a homogeneous mixture of ethanol and 2 mL of acetylacetone, add 6 mL of polyethylene glycol 400 and continue stirring for 1 hour to obtain a titanium dioxide sol. The pretreatment is to soak the glass or conductive glass ITO with distilled water and ultrasonic 20 minutes, immersed in absolute ethanol and sonicated for 20 minutes, washed with acetone, immersed for 4 hours and sonicated for 20 minutes, rinsed in absolute ethanol, immersed in a saturated solution of potassium hydroxide in isopropanol for 24 hours, rinsed in absolute ethanol, immersed in distilled water and sonicated For 20 minutes, rinse twice with water, and finally dry at 100°C.
