A self-foaming polyether sulfone resin and a preparation method therefor. The molecular structure of the self-foaming polyether sulfone resin is represented by formula (I), where 100≤m≤200, 100≤n≤200, and M is Na or K. A high-temperature-resistant polyether sulfone foaming material is prepared with the foaming polyether sulfone resin by simple means such as injection molding and extrusion. The self-foaming polyether sulfone resin has a low density and a high foaming ratio, and can be widely used in the fields such as aeronautics and astronautics, automobiles and electronic and electrical appliances. |
