Abstract: The invention relates to a silk screen printing electrode and a method for synthesizing chloramphenicol molecularly imprinted membrane, belonging to the macromolecule technical field. The invention embeds template molecules in the direct surface in-situ polymerization of a one-time silk screen printing electrode and elutes the template molecules, to form the cavities of fixed sizes and shapes and the function groups of a fixed arrangement in the molecularly imprinted membrane, therefore, the molecularly imprinted membrane has shape memory property to the stereo structure of the template molecules, the chloramphenicol molecule of the object sample can be combined with the cavity specifically, to modify the electromechanical property of the molecularly imprinted membrane to improve the electric conductivity of the molecularly imprinted membrane and improve membrane passing current. The silk screen printing electrode coated with a chloramphenicol molecularly imprinted membrane can be connected with a current sensor to quickly and sensitively detect chloramphenicol density. The molecularly imprinted membrane can be used to detect chloramphenicol, having simple sample pretreatment, short detection time, strong interference resistance and batch production.
