Embodiment 1
[0064] Embodiment 1 A preparation method of a novel ionic liquid functionalized injectable conductive hydrogel, comprising the following steps:
[0065] (1) Poly PBAimBF 4 Preparation of ionic liquids;
[0066] (a) PBAimBF 4 Preparation of ionic liquid:
[0067] Dissolve 1-(3-aminopropyl)imidazole (7mmol, 0.876g) in acetonitrile, add 0.216g NaH at 0°C, transfer it to an oil bath after the reaction for 3h, and after the temperature rises to 80°C, 1,2-dibromoethylene (3mmol, 0.558g) was added dropwise, and the reaction was magnetically stirred for 24h under the protection of N2. After removal of the solvent by rotary evaporation, the product was dissolved in a small amount of methanol and washed three times with anhydrous ether. Subsequently, the product was added to a saturated aqueous solution of sodium tetrafluoroborate and stirred at room temperature for 2 h. After the reaction was stopped, dichloromethane was extracted several times, and diluted AgNo 3 Solution confirm...
