A Netzsch TG‐209 thermobalance (NETZSCH, Germany) was employed for the thermogravimetric analysis (TGA) measurements. Samples were heated at 20°C/min from room temperature (30°C) to 800°C. Dry nitrogen served as both the sweep gas and protection gas at flow rates of 40 mL/min and 20 mL/min, respectively.

The TG‐209 thermobalance is a thermal analysis instrument designed for precise thermogravimetric analysis (TGA). It measures the change in mass of a sample as a function of temperature or time under a controlled atmosphere. The TG‐209 provides accurate and reliable data on weight changes, decomposition, and thermal stability of materials.

The crystallinity of the obtained materials was characterized using the powder X-ray diffraction (PXRD) recorded on a Bruker D8 Discover diffractometer with CuK radiation at a scanning speed of 2 o min -1 .
Attenuated total reflectance Fourier-transform infrared (ATR-FTIR) spectroscopy was performed with a Digilab Excalibur 3100 FTIR spectrometer (Varian), a spectral resolution was better than ± 2 cm -1 .
Scanning electron microscopy (SEM) was performed with a TM-1000 Hitachi (Hitachi Scientific Ltd, Japan) microscope.
Thermoanalytical measurements were carried out using a DSC-204 calorimeter (Netzsch). Standard aluminum crucibles were not sealed, only covered with a lid. The heating rate was 6 K min -1 , gas (argon) flow was 20 mL min -1 . Sample mass ranged from 5.0 to 7.8 mg. The mass loss was measured using a TG-209 thermobalance (Netzsch) in open aluminum crucibles (diameter 8 mm, height 4 mm, mass 120 mg) at a heating rate of 6 K min -1 .
The molecular weight distribution of the samples was determined by gel permeation chromatography on an Agilent 1200 chromatograph with a 1260 Infinity refractive-index detector (30 o C, PL aquagel-OH 40, 300 x 7.5 mm, 0.1 M LiNO3, 1 mL min -1 ). The column was calibrated using standard dextran samples (Sigma-Aldrich, USA). Chromatograms were normalized to the absorption maximum of the refractive-index detector.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
