Ez test compact table top universal tester

The tensile properties of PAzMa1 and PAzMa2 were analysed using a Shimadzu EZ Test Compact Table-Top Universal Tester (Kyoto, Japan). Strips were cut from the polymer films with 5 mm of width, 30 mm of length and 100−120 μm of thick. The samples were dried at 60 °C for 1 h and then immediately measured with an extension rate of 5 or 10 mm·min⁻¹ and a gauge length of 10 mm. At least six samples were tested for each polymer and the data were averaged.

Infrared spectra
(FTIR) were recorded with an FT/IR-4200 FT-IR Jasco Spectrometer with
an ATR-PRO410-S single reflection accessory. High-resolution electron-impact
mass spectrometry (EI-HRMS) was performed on a Micromass AutoSpec
Waters mass spectrometer (ionization energy = 70 eV; mass resolving
power > 10 000). ¹H and ¹³C{¹H}
NMR
spectra were recorded with a Bruker Avance III HD spectrometer operating
at 300 MHz for ¹H, and 75 MHz for ¹³C, using
deuterated solvents such as dimethyl sulfoxide (DMSO-d₆) or deuterated chloroform (CDCl₃) at 25 °C.
Materials were also characterized in terms of their thermal and
mechanical properties. Thermogravimetric analysis (TGA) was performed
on 10–15 mg of sample under synthetic air and nitrogen atmosphere
with a TA Instruments Q50 TGA analyzer, setting the heating rate at
10 °C/min. Differential scanning calorimetry (DSC) used 10–15
mg of the sample under a nitrogen atmosphere with a TA Instruments
Q200 DSC analyzer, 20 °C/min. Tensile tests were performed on
5 mm × 9.44 mm × 0.10 mm samples, using a Shimadzu EZ Test
Compact Table-Top Universal Tester, setting the rate of separation
of jaws at 5 mm/min.
Powder X-ray diffraction (PXRD) patterns
were obtained using a
Bruker D8 Discover (Davinci design) diffractometer operating at 40
kV, using Cu Kα as the radiation source, a scan step size of
0.02°, and a scan step time of 2 s.
