Figure 2. Structural organization, intermolecular interactions, and thermal behavior of P(VDF-TrFE-CFE)/PMMA blend films. (A) XRD patterns of films with different compositions; (B) 1D SAXS profiles; (C) 1D WAXS profiles; 2D WAXS patterns of (D) P(VDF-TrFE-CFE) (E) P(VDF-TrFE-CFE)/PMMA 50/50 wt.%, and (F) PMMA, respectively; (G) FTIR spectra; (H) enlarged FTIR region of the carbonyl band; (I) DSC curves. XRD: X-ray diffraction; SAXS: small-angle X-ray scattering; WAXS: wide-angle X-ray scattering; FTIR: Fourier transform infrared; DSC: differential scanning calorimetry; P(VDF-TrFE-CFE): poly(vinylidene fluoride- trifluoroethylene-chlorofluoroethylene); PMMA: poly(methyl methacrylate); CFE: abbreviation of P(VDF-TrFE-CFE).
