Embodiment 1
[0023] Synthesis of poly-1-naphthylamine hollow nanospheres:
[0024] 10 mmol of 1-naphthylamine monomer and 10 mmol of cetyltrimethylammonium bromide were added to 50 mL of deionized water and stirred to form a light red emulsion. Another 10 mmol of ammonium persulfate was dissolved in 50 mL of deionized water and added to the previously prepared emulsion at a rate of two seconds per drop, and the color of the mixture gradually turned blue and then black. The mixed solution was continuously stirred at room temperature for 24 hours, and a black precipitate formed at the bottom of the cup. The resulting product was alternately washed with deionized water and absolute ethanol for several times until neutral, and placed in an oven at 60° C. for 8 hours to dry to obtain poly-1-naphthylamine nano hollow sphere powder. The yield was 94.1%. The transmission electron microscope pictures of the product are as follows: figure 2 As shown, the hollow spheres have an average size of ab...
Embodiment 2
[0027] Add 2 mmol of 1-naphthylamine monomer and 5 mmol of cetyltrimethylammonium bromide into 50 mL of deionized water and stir to form an emulsion. Another 1 mmol of ammonium persulfate was dissolved in 50 mL of deionized water and added to the previously prepared emulsion at a rate of two seconds per drop, and the color of the mixture gradually turned blue and then black. The mixed solution was continuously stirred at room temperature for 24 hours, and a black precipitate formed at the bottom of the cup. The resulting product was alternately washed with deionized water and absolute ethanol for several times until neutral, and placed in an oven at 60° C. for 8 hours to dry to obtain poly-1-naphthylamine nano hollow sphere powder. The yield was 77.5%.
Embodiment 3
[0029] Add 20mmol of 1-naphthylamine monomer and 30mmol of cetyltrimethylammonium bromide into 50mL of deionized water and stir to form an emulsion. Another 20mmol of ammonium persulfate was dissolved in 50mL of deionized water and added to the previously prepared emulsion at a rate of two seconds per drop. The color of the mixture gradually turned blue and then black. The mixed solution was continuously stirred at room temperature for 24 hours, and a black precipitate formed at the bottom of the cup. The resulting product was alternately washed with deionized water and absolute ethanol for several times until neutral, and placed in an oven at 60° C. for 8 hours to dry to obtain poly-1-naphthylamine nano hollow sphere powder. The yield was 73.9%.
