Example Embodiment
[0025] Example 1-5
[0026] Soak the plastic monolith in 0.2 mmol / L borate buffer solution (pH 7.4), then add 3,4-dihydroxyphenylacetic acid at a concentration of 0.05 mg / mL, and add ammonium persulfate (0.5 mg / mL ). Stir or shake the solution continuously for 7 days, take out the single piece, and repeatedly wash with 50% ethanol aqueous solution to remove unreacted 3,4-dihydroxyphenylacetic acid and unattached poly3,4-dihydroxyphenylacetic acid. Then, the plastic monoliths coated with poly-3,4-dihydroxyphenylacetic acid were immersed in different concentrations of copper nanoparticle solutions (0.001 mMol / L, 1mMol / L, 100 mMol / L, 500 mMol / L, 1 Mol / L). L) After 24 hours (room temperature), after washing the excess salt solution, let the plastic single piece air dry naturally to test the conductivity. The results show that after the growth of copper nanoparticles, a good conductive layer is formed on the non-conductive plastic monolithic surface, and plastic electroplated parts...

[0027] Example 6-9
[0028] Soak the glassy carbon electrode in 1 mmol / L phosphate buffer solution (pH7.0), then add 3,4-dihydroxybenzylamine to a concentration of 100 mg / mL, and add sodium periodate (0.5mg / mL). Stir or shake the solution continuously for 5 minutes, take out the electrode, and repeatedly wash with 50% ethanol aqueous solution to remove unreacted 3,4-dihydroxybenzylamine and unattached poly3,4-dihydroxybenzylamine. Then immerse the glassy carbon electrode coated with poly-3,4-dihydroxybenzylamine in polyaminopyridine solutions of different concentrations (51 mMol / L, 100 mMol / L, 500 mMol / L, 1 Mol / L) 24 After hours (room temperature), the electrode is activated by treatment and the electrochemical behavior of caffeine on the electrode is tested. The results show that the electrode has a good electrocatalytic ability for the electrooxidation reaction of caffeine, and the oxidation peak potential difference increases, so that the motor has a good detection eff...
Example Embodiment
[0029] Example 10
[0030] Soak the forward osmosis membrane in a 10 mmol / L tris (TRIS) hydrochloric acid buffer solution (pH 8.5), and then add 3,4-dihydroxyphenylacetic acid (DOPAC) at a concentration of 2 mg / mL. Stir or shake the solution continuously for 1 hour, take out the forward osmosis membrane, and repeatedly wash with pure water to remove unreacted DOPAC and unattached poly DOPAC. Then, the forward osmosis membrane coated with poly DOPAC was soaked in silver nanosol with a concentration of 100 mMol / L for 10 hours (room temperature), and then the excess salt solution was washed. The antibacterial experiment found that the forward osmosis membrane produced by silver nanoparticles has an antibacterial effect of 100% against a variety of bacteria including Escherichia coli and Streptococcus. The adhesion and growth inhibition efficiency of the forward osmosis membrane to E. coli after the formation of silver nanoparticles reaches 100%.
