The reaction between polyvinylidene fluoride (PVDF) nanofibers and sodium hydroxide in the presence of propan-2-ol (IPA) as phase transfer catalyst (PTC) was studied. In this work; we propose a new reaction mechanism for the formation of the conjugate structure. FTIR and Raman spectra were analyzed with a focus on symmetry basics; which subsequently lead to a clear structure determination and imply that there is in fact an additional hydrogenation step to the dehydrofluorination mechanism previously reported. Sodium isopropylalcoholate catalyzes the Csp2–F bond cleavage in a transfer hydrogenation step and results in the formation of Csp2–H bond; a mechanism supported by the presence of acetone. These findings are of particular importance to PVDF alkaline reaction; it indicates that the use of IPA as PTC alter the reaction mechanism. © 2021;
