Preparation method of polyimide novel material with anticoagulant function

[0018] A preparation method of a new polyimide material with anticoagulant function, the preparation technical scheme is as follows:

[0019] According to the mass parts, add 18 parts of polyethylene glycol and 150 parts of dimethyl sulfoxide to the reaction kettle, stir evenly, control the temperature at 60°C, and then add 70 parts of two sultone compounds containing 5 parts of sultone. The methyl sulfoxide solution was added dropwise to the reaction kettle, and the addition was completed within 40 minutes. The reaction was stirred for 3 hours, and then cooled to room temperature to obtain an intermediate solution for use; 13 parts of cerium-containing polyimide resin powder, 0.3 Add parts of aluminum chloride powder and 150 parts of dimethyl sulfoxide into the reaction kettle, under the protection of nitrogen, heat up to 50°C, stir evenly, add the above intermediate solution dropwise to the reaction kettle, after the addition is complete The temperature is controlled at 70°C, t...

[0027] A preparation method of a new polyimide material with anticoagulant function, the preparation technical scheme is as follows:

[0028] According to the mass parts, 15 parts of polyethylene glycol and 100 parts of dimethyl sulfoxide were added to the reaction kettle. After stirring, the temperature was controlled at 50°C, and then 60 parts containing 2 parts of sultone compound The methyl sulfoxide solution was added dropwise to the reaction kettle, and the addition was completed within 30 minutes. The reaction was stirred for 1 hour, and then cooled to room temperature to obtain an intermediate solution for use; 10 parts of cerium-containing polyimide resin powder, 0.1 Add parts of aluminum chloride powder and 100 parts of dimethyl sulfoxide into the reaction kettle, under the protection of nitrogen, heat up to 40°C, stir evenly, add the above intermediate solution dropwise to the reaction kettle, after the addition is complete The temperature is controlled at 60°C, the re...

[0036] A preparation method of a new polyimide material with anticoagulant function, the preparation technical scheme is as follows:

[0037] According to the mass parts, 20 parts of polyethylene glycol and 200 parts of dimethyl sulfoxide were added to the reactor, after stirring uniformly, the temperature was controlled at 70°C, and then 80 parts of two sultone compounds containing 8 parts were added. The methyl sulfoxide solution was added dropwise to the reaction kettle, and the addition was completed within 60 minutes. The reaction was stirred for 5 hours, and then cooled to room temperature to obtain an intermediate solution for use; 15 parts of cerium-containing polyimide resin powder, 0.5 Add parts of aluminum chloride powder and 200 parts of dimethyl sulfoxide into the reaction kettle, under the protection of nitrogen, heat up to 60℃, stir evenly, add the above intermediate solution dropwise to the reaction kettle, after the addition is complete The temperature is control...
