It can be observed from the figure that before the thermal decomposition of the film, there is a significant weight loss (200-300°C), which can be considered to be the continued imidization and residual solvent volatilization.
It can be observed from the figure that the film has a significant weight loss (200-300 degrees C) before thermal decomposition, which can be thought of as continuing subamineization and residual solvent volatilization.
It can be seen from the figure that there is an obvious weight loss (200-300 ℃) before the thermal decomposition of the film, which can be considered as continuous imidization and residual solvent volatilization.
