a The dynamic infrared spectrum and peak shift of H-bonded N-H groups during heating from 40 °C to 360 °C of PI film. b, c The synchronous and asynchronous infrared spectra of PI film, with red and blue regions representing positive and negative correlation intensities, respectively. d The dynamic infrared spectrum and peak shift of H-bonded N-H groups during heating from 40 °C to 360 °C of PTFMB film. e, f The synchronous and asynchronous infrared spectra of PTFMB film. g H-bonded N-H groups stretching vibration peak positions from 40 °C and 360 °C for different samples. h Stress-strain curve. i Mechanical strength of PI, PABI and PTFMB films. Error bars represent the standard deviations, and the number of replicate experiments for the error bars is 5. j Comparison of mechanical strength among reported dielectric polymers. k Diagram of metallized film capacitor.
