Evaluation of the thermal oxidative stability of polyimides via TGA techniques

Polyimide Films Manufactured Using Partially Wet Electrospray Deposition

“…However, there was a drop in mass at ∼550 °C in both tests, which is attributed to the thermal degradation of the polyimide film itself and not solvent evaporation. Others have reported similar results for the thermal degradation of polyimide and polyimide composites. , These TGA results suggest that there is no residual solvent trapped within the films, at least up to the resolution of TGA instrument (reported as 100 ng with ±0.1% precision).…”

Low-Temperature Terpolymerizable Benzoxazine Monomer Bearing Norbornene and Furan Groups: Synthesis, Characterization, Polymerization, and Properties of Its Polymer

“…Moreover, the typical aromatic carbon in the furan ring, -N-CH 2 -fur, can be found at 47.9 ppm. The findings from the 1 H- 13 C HMQC spectrum (Figure 1c) confirm the precise distribution for the carbons in the norbornene, furan, and oxazine structure in oHPNI-fa. All the above findings confirm the successful incorporation of the furan and norbornene groups into the benzoxazine monomer.…”

Improvement of mechanical, thermal and tribological properties of (3-aminopropyl) triethoxysilane-modified graphene/polyimide nanocomposites by in situ polymerisation

“…For use as a high-performance engineering polymer, the thermal properties of PI under high-temperature conditions are an important property in the evaluation of the modified PI composites [53, 54]. As shown in Figure 8 and Table 1, Compared with the T g (glass transition temperature) of neat PI (246.7°C), the T g of the PMG/PI nanocomposite increased with the loading of PMG increasing.…”
