dc.description.abstractIn this paper a comprehensive first-principles investigation of the structural and energetic stability of poly(trifluoroethylene) (PTrFE) is reported. Using density functional theory (DFT), we systematically analyze the conformational energetics of PTrFE across three structural levels: isolated molecules, infinite polymer strands, and crystalline solids. Various tacticities—atactic, isotactic, and syndiotactic—are explored for each of the known PVDF phases (𝛼, 𝛽, 𝛾) and the 31 helical structure. Our results reveal that while the isotactic 31 helix is the most stable conformation, planar 𝛽 and 𝛾 phases become energetically favorable in atactic or syndiotactic crystalline environments, where intermolecular interactions and steric minimization dominate. In addition, simulated X-ray diffraction (XRD) patterns are compared with those found in the literature, revealing characteristic features to distinguish different phases and chain arrangements.en
