Characterization of Lignin-Based Polymers

Check if the same lab product or an alternative is used in the 5 most similar protocols
The number-average molecular
weight (Mn) and dispersity (Đ) of the synthesized polymers and MBM were
obtained using a Viscotek VE2001 size-exclusion chromatography (SEC)
instrument with THF (Optima) as the eluent (1.0 mL min–1) and polystyrene standards (1.78–205 kg mol–1) as the reference. Glass transition temperatures (Tg’s) of all polymers were determined using a differential
scanning calorimeter (DSC, Discovery Series, TA Instruments). The
thermal degradation behavior of SaBSa was characterized using thermogravimetric
analysis (TGA, Discovery Series, TA Instruments). Further details
of thermal analysis are located in the Supporting Information. Tensile testing on lignin-based polymers was performed
using dog-bone-shaped testing bars (following ASTM D638, bar type
5, 5.3 mm gauge width, 0.8 mm thickness) that were prepared by compression
molding into a Teflon PTFE sheet (McMaster Carr) on a PHI hot press.
Tensile testing was performed with a RSA-G2 solids analyzer (TA Instruments)
in tension mode. Tensile testing on MBM also was performed for comparison,
except that the testing specimens were prepared with an aluminum mold.
Detailed protocols are provided in the Supporting Information.

Thermal transitions were measured in the range −150 °C to 180 °C at a heating rate of 20 °C min−1, on a differential scanning calorimeter (DSC) Discovery series from TA Instruments. Thermogravimetric analysis (TGA) was performed from room temperature to 700 °C at a heating rate of 10 °C min−1 and an inert atmosphere on a thermogravimetric analyser Discovery series (TA Instruments).

Thermal Analysis of Material Samples

Check if the same lab product or an alternative is used in the 5 most similar protocols
The thermal behavior of the samples was evaluated by DSC and TGA on a TA-instrument, Discovery® series equipped with a data station (Trios® software, TA Instruments, New Castle, USA). TGA curves were obtained in the temperature range of 25-350°C in a dynamic N 2 atmosphere (50 mL/min) at a heating rate of 10°C/min. DSC was performed on samples (2.2-3.2 mg) heated in nonhermetic aluminum pans with pin holes and heated from room temperature to 225°C under dynamic N 2 atmosphere (50 mL/min) at a heating rate of 10°C/min.

The synthesized
sulfur copolymers were characterized by X-ray diffraction (XRD), differential
scanning calorimetry (DSC), and Fourier transform infrared (FTIR)
spectra.
The diffraction (XRD) patterns were collected using
an analytical X’Pert PRO Powder Diffractometer (Cu Kα
radiation 1.5406 Å, 40 kV, 40 mA) in the range of 5–80°
2θ scale, with a step size of 0.02°. The DSC analysis was
carried out on a Discovery series (TA instruments) for temperatures
ranging from −30 to 200 °C at a ramp rate of 10 °C/min
under nitrogen atmosphere.

Thermal behavior was evaluated by DSC and thermogravimetric analysis (TGA) in a TA®-instrument, Discovery series equipped with a data station (Trios® software, v4.1.1, TA Instruments) . DSC was performed on samples (0.9-1.7 mg) heated in non-hermetic aluminum pans with a pine hole, using heating ramp of 10 °C/min from 15 to 200 °C, under N 2 flux (50 mL.min -1 ). TGA was performed on samples (approximately 2 mg) placed in open aluminum pans and heated from room temperature to 300 °C under the conditions used in DSC analysis.

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.
