Embodiment 1
[0020] At room temperature, wash and dry about 0.7g of polyurethane foam containing hydroxyl groups (6 pieces, about 1cm in size) 3 ) into 1mg / ml graphene oxide aqueous solution and let it stand for 5 minutes, take it out, dry it, wash it and dry it, then put it into 80mL of 2mmol / L sodium hydroxide solution, add 20ml diethylenetriamine, and stir for 3 hours , rinsed with distilled water and dried. Reserve 10ml of the original reaction solution and add water to dilute it to 100ml, add 1ml / L ammonia water, transfer the graphene oxide modified polyurethane foam and 100ml diluted solution to a 500mL flask with a stirrer, heat up to 98°C and react for 1h , rewashed with distilled water and dried to obtain ammoniated graphene oxide modified polyurethane foam. In a 500mL flask with a stirrer, add 0.7g of ammoniated graphene oxide modified polyurethane foam and 100mL of 2mmol / L NaOH solution, dissolve 0.2mM anthraquinone-2-sulfonyl chloride in 25mL of dichloromethane , and then add...
Embodiment 2
[0022] At room temperature, wash and dry about 0.7g of polyurethane foam containing hydroxyl groups (6 pieces, about 1cm in size) 3) into 1mg / ml graphene oxide aqueous solution and let it stand for 5 minutes, take it out, wash and dry after drying, repeat the above procedure 3 times, then put it into 50mL of 2mmol / L sodium hydroxide solution, add 50ml of diethylenetri Amine, stirred and reacted for 6 hours, rinsed with distilled water and dried. Keep 4ml of the original reaction solution and add water to dilute it to 100ml, add 1ml / L ammonia water, transfer the graphene oxide modified polyurethane foam and 100ml diluted solution to a 500mL flask with a stirrer, heat up to 98°C and react for 1h , rewashed with distilled water and dried to obtain ammoniated graphene oxide modified polyurethane foam. In a 500mL flask with a stirrer, add 0.7g of ammoniated graphene oxide modified polyurethane foam and 100mL of 2mmol / L NaOH solution, dissolve 0.4mM anthraquinone-2-sulfonyl chlorid...
