Tga dsc 3

Thermogravimetric analysis (TGA) was carried out using a Simultaneous TGA/differential scanning calorimetry (DSC) analyzer (TGA/DSC 3+, Mettler Toledo, Greifensee, Switzerland) with temperature scanning from ambient to 800 °C at a heating ramp of 10 °C/min. Besides this, TDT for all samples was defined as the temperature where 50% of weight loss was viewed. Also, the thermal stability of samples was evaluated by differential scanning calorimetry (DSC, TGA/DSC 3+, Mettler Toledo, Switzerland) while flowing N₂ over a range of 25–800 °C and with a heating rate of 10 °C/min. In addition, the thermal conductivity was evaluated by using Thermal Constants Analyzer (TPS-500s, Hot Disk AB Co., Gothenburg, Sweden) at room temperature under 20 mW within 10 s.
The compressive properties measurements were carried out using an electronic universal testing machine (Inspekt table blue 5 kN, Hegewald & Peschke, Nossen, Germany) at a testing speed of 1 mm/min for all samples according to the ASTM D1621-16 standard. The sample size is 40 mm × 20 mm × 16 mm.
All the above tests were performed on at least five samples from each set of measurements.

The Fourier transform infrared (FT-IR) spectra of the polymers were tested by the JASCO IR-4100 spectrometer (JASCO, Tokyo, Japan). The solid-state ¹³C cross-polarization with magic-angle spinning (CP/MAS) results were collected by a 599.7 MHz nuclear magnetic resonance spectrometer (JNM-ECZ600R, Agilent, Santa Clara, CA, USA). Powder X-ray diffraction (PXRD) results were obtained by using a Rigku D/max-2400 diffractometer (40 kV, 200 mA) from 5° to 80° with a scanning rate of 2°/min (Bruker AXS, Madison, WI, USA). The scanning electron microscopy (SEM) analysis was examined by using HITACHI-SU5000 (HITACHI, Tokyo, Japan). The results of the adsorption and desorption of N₂ were obtained by an analyzer called Quantachrome-Autosorb IQ (Quntachrome, Kanagawa, Japan). The thermogravimetric (TGA) analysis was executed by using Mettler Toledo TGA/DSC 3+ (Mettler Toledo, Greifensee, Switzerland) under a nitrogen atmosphere. Samples were heated from 25–800 °C with a 10 °C/min heating rate. The ultraviolet (UV) spectra of the polymers were measured by the JASCO V-750 (JASCO, Tokyo, Japan). The X-ray photoelectron spectroscopy (XPS) analysis was examined by using ESCALAB XI+ (thermo, Oxford, UK).

Thermogravimetric analyses were performed using a Mettler Toledo TGA-DSC 3+ (Mettler-Toledo, LLC, Columbus, OH, USA) instrument. Samples were heated from 25 °C to 900 °C at 10 °C min⁻¹ with nitrogen flow of 30 mL min⁻¹. Alumina crucibles with 900 µL volume were used.
