Abstract

AbstractThe stability of polymer materials used in nuclear environment directly determines the life and reliability of nuclear power equipment. Poly (aryl ether ketone) (PAEK) itself exhibits excellent irradiation resistance which can be widely used. The emphasis of this study lies in designing and synthesizing three different structures of amorphous PAEKs by the solution SN2 nucleophilic polycondensation. The thermodynamic properties and structural changes of the materials under gamma‐ ray (γ‐ray) irradiation were investigated and the irradiation‐resistance mechanism was discussed. The present results illustrate that the performance can be basically stable lower than 108 Gy. Up to 1013 Gy dose, γ‐ray has little effect on the impact resistance and Young ′s modulus of the three materials, the tensile strength and elongation at break decreased with the increase of irradiation dose. No new structures were formed after irradiation, and all the three materials decomposed slightly caused by oxidized.
