Embodiment Construction
[0020] The present invention is further described in detail through the following examples, but the technical content described in this example is illustrative rather than limiting, and should not limit the protection scope of the present invention accordingly.
[0021] The best embodiment: take 0.5mmol of the template molecular compound penicillin and dissolve it in 5mL of inert solvent N, N-dimethylformamide solution, add 2.0mmol of functional monomer methacrylic acid (MAA), place on a shaker to vibrate 6h, so that the template molecules and functional monomers fully act. Then add cross-linking agent ethylene glycol dimethacrylate (EDMA) 10mmol, initiator azobisisobutyronitrile (AIBN) of 0.0125g, transfer to a 15mL test tube after mixing, nitrogen deoxygenation 10min, seal under vacuum Then put it in a constant temperature water bath, react at 60°C for 24 hours to form a rod-shaped polymer, and then crush and grind the polymer with a mortar and sieve. : 1)] ultrasonic washi...
