To identify the prepared solid phase, TG-DSC (analysis was performed using a Jupiter STA 449 F5 thermoanalyzer (Netzsch, Selb, Germany) with gaseous decomposition products identified in a Vertex 70v infrared spectrometer from Brüker Optik coupled to the thermoanalyzer. To perform this analysis, a stable sample was exposed to temperature. During this time, the thermoanalyzer time and temperature-dependent changes in the mass of the sample were recorded. The decomposition products were transported by capillary to the IR spectrometer, where they were analyzed in the infrared absorption spectra.

Thermogravimetric Analysis of Irradiated Samples

The thermogravimetric analysis (TGA) of all samples (non-irradiated and UV-irradiated) was performed on the Jupiter STA 449 F5 thermoanalyzer by Netzsch coupled with the FT-IR Vertex 70V spectrometer by Bruker Optik in the following conditions: a nitrogen atmosphere, a temperature range of 20–600 °C, and a heating rate of 10°/min. The weight of the samples was 6–10 mg. The simultaneous measurement of TG, DTG, and DSC allowed for the determination of the following parameters: decomposition onset temperature (T0), temperature (Tmax) at the maximum process rate (Vmax), weight loss (∆m) for individual stages, and heat effects (ΔH) accompanying the decomposition. The mixture of volatile products, released at temperatures ranging from room temperature to 600 °C, was analyzed based on the infrared spectra recorded in the range of 400–4000 cm−1. The evolved gases were transported to the gas cell (with ZnSe spectrophotometric windows) in an FTIR spectrophotometer. The connections between the thermoanalyzer and spectrophotometer were heated to 200 °C to prevent condensation. The carrier gas shows no infrared absorption.

Thermal Analysis of Material Properties

Simultaneous thermogravimetric analysis (STA) was carried out on a NETZSCH STA 449 F5 Jupiter instrument (Berlin, Germany) using about 5–10 mg of the sample. The sample was placed in an alumina crucible and heated from 25 to 800 °C with a heating rate of 10 °C/min under nitrogen atmosphere, with a flow rate of 50 mL/min. In addition, differential scanning calorimetry (DSC) was carried out by using a Q200 V24.11 Build 124 TA instrument (New Castle, Delaware, USA). In a typical measurement, approximately 0.5 g of the sample was dispersed in DI water (the ratio 1:4 = sample: water) and stirred for 1 h. A small amount (5 mg) of dispersion was then placed in the pan and heated from 25 to 250 °C (a heating rate of 5 °C/min) under nitrogen atmosphere to observe the gelatinization temperature.

Thermal Analysis of R3 Samples

For analyzing the reaction processes of the R3 samples, the samples were tested both by TGA and by a calorimeter.
For thermogravimetric analysis (TGA), “STA 449 F5 Jupiter” from NETZSCH (Selb, Germany) was employed. The crucibles consisted of alumina and were filled with 40–50 mg of powder material. To avoid oxidation, nitrogen was used as an inert gas. The samples were first heated up to 40 °C and kept constant at this temperature for 30 min. Subsequently, each sample was heated up to 1000 °C at a constant heating rate of 20 °C per minute.
For the calorimetric measurements, “MC CAL” from C3 Prozess- und Analysentechnik GmbH (Haar, Germany) was employed. For this, 20 g of R3 sample were prepared at room temperature and placed in the calorimeter ampoule, which was preconditioned at 40 °C. Measurements of the heat release of the R3 samples were carried out for seven days. The reference sample was used for the calculation of the specific heat capacity.

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.
