Embodiment 1
[0039] In this embodiment, the sulfonamidated polyaromatic polymer is a polymer with polyether ether ketone as its main chain and benzenesulfonamide groups as its side chains. The polymer uses polyether ether ketone as raw material, sulfuric acid as sulfonation reagent, thionyl chloride as acyl chloride reagent, liquid ammonia as amidation reagent, and is prepared through reactions such as acyl chloride and amidation.
[0040] Concrete preparation method comprises the following steps:
[0041] Step 1: In a 50ml three-neck flask, add 20ml of concentrated sulfuric acid with a concentration of 98% by mass, then stir and add 1g of polyether ether ketone resin powder, heat up to 40°C, and perform sulfonation reaction for 12h; after the reaction, pour the reaction product into ice water, the resin is precipitated, and fully washed with deionized water to obtain sulfonated polyether ether ketone resin.
[0042] Step 2: Add the sulfonated polyether ether ketone resin obtained in step...
Embodiment 2
[0049] In this embodiment, the sulfonamidated polyaromatic polymer is a polymer with polysulfone as its main chain and benzenesulfonamide groups as its side chains. The polymer is prepared by taking polysulfone as raw material, chlorosulfonic acid as sulfonating reagent and acyl chloride reagent, ammonia as amidation reagent, and is prepared through reactions such as acyl chloride and amidation.
[0050] Concrete preparation method comprises the following steps:
[0051] Step 1: In a 50ml three-neck flask, add 20ml of dichloromethane, then stir and add 1g of polysulfone resin particles, after dissolving, slowly drop in 3ml of chlorosulfonic acid dissolved in 10ml of dichloromethane, and put it in an ice-water bath React for 3 hours; after the reaction, pour the reaction product into ice water to precipitate the resin, wash it thoroughly with deionized water, and freeze-dry to obtain the sulfonyl chloride polysulfone resin.
[0052] Step 2: Put the sulfonyl chloride polysulfon...
