Embodiment 1
[0043] 1) 400 μL of a chloroform solution of 2 mg / mL conjugated polymer PCPDTBT and 2.5 mL of an aqueous solution of 1 mg / mL cetyltrimethylammonium bromide were uniformly mixed by stirring and ultrasonic treatment to form an emulsion;
[0044] 2) heating the emulsion obtained in step 1) in a water bath at 60° C., and obtaining a clear and transparent PCPDTBT aqueous solution after the chloroform is completely evaporated;
[0045] 3) Stir 1 mL of 2-methylimidazole aqueous solution with a concentration of 1.32 mol / L for 10 minutes;
[0046] 4) Add 200 μL of cetyltrimethylammonium bromide aqueous solution with a concentration of 1 mg / mL and 200 μL of the PCPDTBT aqueous solution obtained in step 2) to the 2-methylimidazole aqueous solution obtained in step 3) and stir for 10 minutes to obtain a mixed solution;
[0047] 5) Add 1 mL of an aqueous solution of zinc nitrate nonahydrate with a concentration of 24 mmol / L to the mixed solution obtained in step 4) and keep stirring for 1...
Embodiment 2
[0051] 1) Stir 1 mL of 2-methylimidazole aqueous solution with a concentration of 1.32 mol / L at 20°C for 10 minutes;
[0052] 2) Add 400 μL of cetyltrimethylammonium bromide aqueous solution with a concentration of 1 mg / mL to the 2-methylimidazole aqueous solution obtained in step 1) and stir for 10 minutes to obtain a mixed solution;
[0053] 3) Add 1 mL of an aqueous solution of zinc nitrate nonahydrate with a concentration of 24 mmol / L to the mixed solution obtained in step 2) and keep stirring for 10 minutes to obtain a reaction solution;
[0054] 4) The reaction solution obtained in step 3) was allowed to stand naturally at room temperature for 24 hours, and the precipitate was collected by centrifugation and washed three times with methanol to obtain the organometallic framework material ZIF-8 dispersed in methanol.
[0055] The experimental results show that, if Figure 4 As shown, the obtained ZIF-8 composite nanoparticles are square about 50 nm in size, have no pores i...
