The present invention discloses a kind of polypyrrole/graphene oxide composite material and its preparation method and application of polymeric ionic liquid modification containing phenyl boric acid.GO is synthesized first, and then pyrrole monomer Py and GO obtains PPy/GO by Hydrogenbond, then chloropropene is connect on the surface PPy/GO by substitution reaction, obtains intermediate PPy/GO-CH 2 - CH=CH 2 ；N- vinyl imidazole occurs vinyl polymerization with intermediate in chloroform and reacts, and obtains polypyrrole/graphene oxide (PVI/PPy/GO) of poly- (N- vinyl imidazole) modification；PVI/PPy/GO is reacted with 4- bromomethyl benzene boric acid, obtains P (4VMIB-PBA)/PPy/GO.Composite material prepared by the present invention can be used for the preparation of electrochemical sensor, identifies and detects while realizing to dopamine and paracetamol, and have good stability, sensitivity and lower detection limit. |
