Embodiment 1
[0017] In the present embodiment, the preparation method of the antibacterial coating based on polyimidazolium salt, concrete steps are as follows:
[0018] (1) Taking the silica gel sheet as an example, the surface area selected here is 0.25cm 2 The substrate pretreatment steps: first, wash with water and absolute ethanol in turn, repeat 3 times and then dry in a 30°C oven for 24 hours; second step, prepare solution A: 1g of epoxy resin and 9mL of Mix dichloromethane, put in the silica gel sheet, soak it, then take it out and dry it in an oven at 30°C for 30 minutes, repeat the above steps twice; finally, prepare solution B: dissolve 1g of azobisisobutyronitrile in 9ml of acetone, mix A, Mix B solutions (A:B=1:0.5), put the silica gel sheet into the mixed solution, soak it, take it out and dry it in an oven at 30°C for 24 hours, and produce a coating with an initiator on the surface of the silica gel sheet.
[0019] (2) Select acrylic acid for use, and prepare the transition...
