- •
TGA/MS results revealed that IFR could reduce the releasing rate of NH3 at first stage with more uniform rate.
- •
The side chain fragmentation was the major mechanism of thermal degradation in this thermal degradation step.
- •
The IFR system reduced the decomposition rate of polymer chain and presented excellent smoke suppression ability.
- •
Appropriate graphitization degree and connected structures of the char were formed.
