| Abstract: |
| The physical aging of fluoropolymer F2314 was studied by differential scanning calorimetry （DSC） and dynamic mechanical analysis.The results showed that，as the time of physical aging at 45 ℃ prolonged，the storage modulus of F2314 increased，the loss factor was decreased；the enthalpy of DSC absorption peak had no significant change，but the peak position moved towards higher temperature zone；the relaxation modulus increased and the amplitude increased gradually. |
