EXPERIMENTAL

• Determination of the glass transition temperatures by DSC

  • the glass transition temperatures were taken as the midpoint of thermal transitions determined in heating scans at a rate of 20°/min

• Determination of mechanical properties by stress-strain measurements

  • tensile properties were determined fixing a crosshead speed of 50 mm/min

• Evaluation of the water absorption by EIS

  • the data were collected at frequencies ranging from 1 kHz to 40 kHz at voltage amplitudes of 10 mV

• Evaluation of the degradation by EIS

  • the data were collected at frequencies ranging from 50 mHz to 100 kHz at voltage amplitudes of 20 mV
