The invention provides a flexible electrode-based molecularly imprinted electrochemical sensor making method. The method comprises the following steps: self-assembling acrylate-co-styrene styrene random copolymer with p-nitrophenol as a template molecule through combining macromolecular self-assembling, molecular imprinting and electrophoretic deposition technologies to obtain p-nitrophenol coated imprinted micelles, placing a PET conductive electrode as a working electrode, a platinum plate electrode as a counter electrode and a saturated calomel electrode as a reference electrode in a imprinted micelle solution, depositing through a controlled potential electrolysis technology to form a film on the electrode surface, carrying out ultra violet radiation crosslinking on the film under the action of a photoinitiator, and eluting to remove p-nitrophenol in order to obtain a molecularly imprinted sensing electrode. The sensor has good flexibility and portability. The invention also provides a new making idea of molecularly imprinted sensing flexible devices. The application field of the molecularly imprinted sensor is widened, and new ideas are provided for exploitation and application of wearable, folding and patterned flexible molecularly imprinted sensing electron equipment.
