Embodiment 1
[0029] A preparation method of titanium dioxide composite nano antibacterial material, comprising the following steps:
[0030] (1) Preparation of Enteromorpha nano-dry powder: After the fresh Enteromorpha is washed to remove impurities such as sand grains, freeze-dried to obtain a dry product, the obtained dry product is ultrafinely pulverized to a 500-mesh micron powder, and the obtained micron powder is placed in a ball mill tank for further processing High-energy ball milling, wherein the mass ratio of zirconia balls: micron powder: water is 8:4:1, the rotating speed is 2500 rpm, and the ball milling time is 3 hours. The obtained powder is placed in a 60°C oven and dried to obtain Enteromorpha nano dry powder;
[0031] (2) Preparation of spinning precursor solution: add 3.4g of n-butyl titanate and 2g of sulfosalicylic acid into 9ml of absolute ethanol, stir for 1 hour and mix evenly, then add 2.2g of enteromorpha nano dry powder obtained in step (1) , magnetically stirred...
