The phase behavior of the formulations was evaluated with a Discovery DSC 2500 (TA Instruments, Leatherhead, UK), equipped with a refrigerated cooling system (RCS 90) and a dry nitrogen purge with a flow rate of 50 mL/min. Calibration for temperature, enthalpy and heat capacity was carried out using indium and sapphire standards, respectively. The following parameters were applied for the mDSC measurements: a linear heating rate of 2 °C/min combined with a modulation amplitude of 0.212 °C and a period of 40 s. Approximately 1–3 mg of the sample were accurately weighed into standard aluminum DSC pans (TA Instruments, Zellik, Belgium), followed by crimping with standard aluminum DSC lids (TA Instruments, Zellik, Belgium). All samples were isothermally held at 40 °C for 30 min, followed by a heating procedure ranging from −20 to 120 °C. DSC thermograms were analyzed using Trios software (Version 5.1, TA Instruments, Leatherhead, UK). Glass transition temperatures (Tg) were measured at half height of transition in the reversing heat flow (RHF).

Differential Scanning Calorimetric analysis was performed using a TA Instruments® Discovery DSC2500, New Castle, DE, USA. DSC analysis was performed on all the heat-treated samples as well on the as-received wire to study the phase transformation temperatures. The crucibles used for this experiment were made of pure aluminum, which is suitable for solid and powder samples that do not decompose or boil at temperatures between −170 °C to 600 °C [32 ]. The tests were conducted in the temperature range of 0 °C to 150 °C with a ramp up rate of 10 °C/min. The austenite and martensite start and peak and finish temperatures were evaluated. TZero aluminum pan with TZero lids and a sample mass of around 20 mg were used to carry out the tests. Liquid nitrogen was used as the cooling medium.

DSC measurements under nitrogen and under air were conducted for the regenerated neat PAN and PAN/lignin fibers using Discovery DSC 2500 from TA Instruments (TA Instruments (Water Corporation, New Castle, USA) with Fusion CellTM technology for flat baseline. The stabilization procedures were performed under air to mimic the stabilization process and under nitrogen to reveal the stabilizing role of lignin on the stabilization process of the developed fibers. The weight of the samples was between ~3 and 3.5 mg. All samples were pre-dried under vacuum for 24 at 80 °C and stored in a sealed desiccator over silica gel pellets prior to any measurement. Heating rates of 1, 2, 5, 7, and 10 K·min−1 were selected for the DSC measurements.

Since the materials in the study are commercial grades, with limited information on the compositions, the materials were subjected to a thermal analysis.
Differential scanning calorimetry (DSC) was performed with a Discovery DSC 2500 (TA Instruments, New Castle, DE, USA). The heating/cooling rate was 20 °C/min. Heating and cooling in the interval −70 °C to 200 °C were performed twice.
Thermogravimetric analysis (TGA) was performed with a Discovery TGA 550 (TA Instruments), following ISO 9924-3 with minor adjustments: The carbon-based elastomers (TPV and EPDMs) where heated in nitrogen to 600 °C and cooled to 400 °C, before switching to air and heating to 900 °C. The isothermal holding times at 600 °C, 400 °C and 900 °C were 2 min, 2 min and 30 min, respectively. The LSR was analysed in a similar way, but it was heated to 800 °C in the first step.

A reactive surfactant solution of 3.2 grams (Hitenol BC1025 from Montello), 72 grams deionized water, and 0.8 g NaHCO3 was prepared by mixing in a glass reactor. The reaction was then purged with nitrogen for 30 minutes. The reactor was then continuously purged with nitrogen while being stirred at 250 rpm. The reactor was then heated up to 85° C. and held there. Separately, 0.2 grams of ammonium persulfate (APS) initiator was dissolved in 5 grams of deionized water and added to the reactor.

Heat capacity was measured via differential scanning calorimetry (DSC; Discovery DSC 2500, TA instruments) of one sample for each OSZ content according to the American Society for Testing and Materials E1269-11 standard. All samples were ground to a powder before the measurement to ensure good contact with the DSC pans. Two heating cycles between −40° and 200°C were performed with a 20 K/min heating rate. Only the second heating cycle was evaluated. The measurement was repeated four times. The final value is the average of all measurement runs at 23°C.

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.
