a, b IR-PiFM measurements of P3 + 10% 2DPA films: topography and phase images. c Infrared absorption spectra of 2DPA and P3. d, e Corresponding AFM-IR chemical maps under irradiation at 1750 cm−1 and 1110 cm−1. f Normalized full IR spectrum of corresponding AFM-IR chemical maps (d: 1750 cm−1, e: 1110 cm−1). g Normalized full IR spectrum of corresponding AFM-IR chemical maps for P3 and P3 + 10% 2DPA films. h Infrared spectra of P3, 2DPA, and P3 + 2DPA composite. i Peak fitting at 1250 cm−1 and quantification of conformations contributed by 2DPA in the composite film.
