Both polymers presented onsets of degradation (at 5% weight loss) at ~360°C and maximum rate of weight loss (DTG peak) at approximately 460°C.
In this temperature range, a maximum rate of weight loss was shown at 225°C, and the total weight loss was approximately 27 wt.%.
For the HFRUP composites, the maximum rate of weight loss was 0.81%/°C.
Thermal stability of the printed composites was also improved, as shown by increases in the temperature at maximum rate of weight loss and the glass transition temperature.
The response variables (biochar yield, fixed-carbon yield, and the temperature at which the maximum rate of weight loss is reached) were analysed using regression models.
For the NaOH treated and glass fibre hybridised hemp/UP composites, the maximum rate of weight loss was 0.78%/°C and 0.79%/°C, respectively.
The temperature at the maximum rate of weight loss at the second stage of decomposition (Td,max2) of ZHS/PVC, GO/PVC, and ZHS/GO/PVC were obviously higher than that of PVC.
The peak temperature which is the point on the burning profile at the maximum rate of weight loss is usually denoted as a reactivity measurement of the sample (Haykırı-Acma et al. 2001).
The temperature at the maximum rate of weight loss at the second stage of decomposition (Td,max2) of ZHS/PVC, GO/PVC, and ZHS/GO/PVC was obviously higher than that of PVC.
Among the parameters investigated, the maximum rate of weight loss at the stage of acetic acid evolution was found to have a linear relationship with VA content and to be independent of molecular weight and heating rate.
