Simultaneous Small and Wide Angle X-ray Scattering experiments (SAXS and WAXS) were performed “in situ” under “operando” conditions. The X-ray experiments clearly reveal the presence of a polar phase in the PVDF-HFP/EG while for PVDF-HFP its presence is not obvious. Complementary Fourier Transform Infrared Spectroscopy experiments corroborate the presence of the polar phase for both materials. For PVDF-HFP crystallization is faster at the interfaces (polymer-air and polymer-polymer) than in other points within a printed line, being the crystallinity lower at the interfaces. However, for the PVDF-HF composite, neither crystallization rate nor crystallinity is dependent on position. The effect of EG, acting as nucleating agent, has been discussed as being the reason for this behavior.This work has been funded by grants PID2022-138635NB-I00 funded by MCIN/AEI/10.13039/501100011033 and TED2021-131914B–I00 and TED2021-129845B–I00 funded by MCIN/AEI/10.13039/ 501100011033 and by “ERDF A way of making Europe", and by the Regional Government of Madrid through the project TEC MATRIX-CM (TEC-2024/TEC-85).
