preparation example 1
[0050] This preparation example provides a silane coupling agent modified nanoparticle I, which is prepared by the following preparation method:
[0051] (a) After uniformly mixing 200 mg of isopropanol and 20 mg of deionized water, add 20 mg of silane coupling agent KH570, and fully stir at 25°C for 2 hours to obtain a silane coupling agent dispersion;
[0052] (b) in the silane coupling agent dispersion that step (a) obtains, add the nanometer TiO of 200mg 2 , fully stirred at 25°C for 2h, filtered, and dried in an oven at 100°C for 6h to obtain silane coupling agent-modified nanoparticles I.
