Thermal decomposition was followed in terms of weight loss to evaluate the thermal stability of the raw materials. The tests were performed on a model Q5000IR from TA Instruments (New Castle, DE, USA). Samples between 10 and 20 mg were analyzed with a heating rate of 10 °C/min between 50 and 500 °C. To evaluate the thermal and oxidative resistance under a nitrogen atmosphere.
Q5000ir
Manufactured by TA Instruments
Sourced in United States, United Kingdom
The Q5000IR is a thermogravimetric analyzer (TGA) that measures the weight change of a sample as a function of temperature or time in a controlled atmosphere. It can be used to analyze a variety of materials, including polymers, ceramics, and composites. The Q5000IR provides accurate and reliable data on thermal stability, composition, and kinetic parameters.

Given that polymers undergo heating during 3D printing, thermal degradation behavior of polymer, hormones and the 3D printed constructs were studied using TA Instrument Q5000 IR. The samples were tested using ramp method. Samples were heated from ambient temperature to 500°C at a rate of 20°C/min and changes in sample weight were measured. Changes in melting temperatures (Tm) and glass transition temperatures (Tg) of polymers due to addition of hormones were tested using DSC. Samples were heated from -80°C to 130°C at a rate of 10°C/min. Energy input (heat flow) was measured as a function of temperature in this analysis. Both analyses were carried out in a nitrogen environment.

A thermobalance, model Q5000IR (TA Instruments; New Castle, DE, USA) was used for TGA investigations. Temperature calibration was based on the Curie point of paramagnetic metals. A multipoint calibration with five Curie points from reference materials (Alumel, Ni, Ni 83%-Co 17%, Ni 63%-Co 37%, Ni 37%-Co 63%) was performed. TGA measurements were carried out at a heating rate of 10 °C/min from 25 to 700 °C under nitrogen flow (25 mL/min). The amount of sample in each measurement varied between 0.8 and 1.2 mg. TA Universal Analysis software was used in the data analysis of the thermograms. Triplicate analyses provided a 0.1% relative standard deviation.

The topography of GO flake and GO/SF/LiBr composite was characterized using an AFM (Cypher VRS, Oxford Instruments.) and Cryo-SEM (Quanta 450, FEI). Each experiment was repeated three times independently and produced similar results. The rheological properties of the GO/SF/LiBr inks were measured by a rheometer (MCR 301; Anton Paar). The viscosities of the ink were recorded within a shear rate from 10−1 to 103 s−1. The thermal stability and water content (11.3% RH) of the GO/SF/LiBr ink were characterized using a thermogravimetric analyzer (Ar, 10 °C/min, Q5000IR, TA Instruments). Raman spectra of the GO were collected using a Raman spectroscope (Horiba HR800, 532 nm). X-ray photoelectron spectra (XPS) of graphite paper and GO were collected using a PHI Quantera SXM (ULVAC-PHI) scanning X-ray photoelectron spectrometer microprobe.

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.
