Dynamic mechanical analysis (DMA) was performed using a TA instruments DMA 950 device. Strips with dimensions of 20 x 3 x 2 mm were 3D printed for each measurement. The measurements were conducted with a tensile test configuration in a temperature range of 10 to 150 °C with a ramp of 3 °C/min and a frequency of 1 Hz. The amplitude was set to 0.01% after an amplitude sweep of all three samples. Fourier transform infrared spectrometry (FTIR) spectra were recorded on a JASCO FT/IR-4600 FT-IR spectrometer in a range of 500 -4000 cm -1 .
