Embodiment 1
[0067] A preparation method of nano titanium dioxide, comprising the following steps:
[0068] (1) Synthesis of star macromolecular initiator 21Br-β-CD:
[0069] Take 6.82g of β-cyclodextrin, dry it at 80°C for 12h under vacuum, then dissolve it in 60mL of N-methylpyrrolidone at room temperature, put it in an ice-water bath, and cool it to 0°C. Under this condition, Add 58g of 2-bromoisobutyryl bromide dropwise within 2h. After the dropwise addition, warm up to room temperature and continue to react for 24h to obtain a brown solution. Concentrate by distillation under reduced pressure, add 100mL of dichloromethane to dilute, and wash with 100mL of saturated aqueous sodium bicarbonate solution and 100 mL of deionized water were washed three times each, and the obtained organic phase was dried with anhydrous magnesium sulfate, then concentrated with a rotary evaporator, and finally precipitated in n-hexane below -20°C to obtain a white precipitate, which was dried in a vacuum ov...
Embodiment 2
[0093] A nano-silver synthesis method, the steps of which are similar to the method of nano-titanium dioxide, the difference is that the nano-silver is the synthesized multi-arm star-shaped block copolymer β-CD-g-[PAA-b-PEG] and precursor AgNO 3 reaction, the steps are:
[0094] Dissolve 10 mg of multi-arm star-shaped block copolymer β-CD-g-[PAA-b-PEG] in 10 mL of DMF to make unimolecular micellar template solution; then add 58.9 mg of AgNO 3 And ethanol 2mL, at 100 ℃ for 10h, that is.
[0095] TEM images of silver nanoparticles image 3 As shown, it can be seen that the size of the nanoparticles is uniform, and the average particle diameter is about 10 nm.
[0096] The solubility of Ag nanoparticles in water was detected, and the results were as follows: Figure 4 As shown, it can be seen that the Ag nanoparticles prepared by the present invention have good solubility.
