WebA β-phase PVDF is prepared through a controllable dehydrofluorination under either a basic or high temperature condition. PVDF is degraded by losing hydrogen fluoride (HF) and either carbon-carbon double bonds form in the molecular backbone or single bonds form crosslinking the two polymer chains. These changes in structure influence the … WebFeb 13, 2024 · The loose DL PVDF HFMs was then further cross-linked through a one-pot amine-based reaction. The cross-linking reaction for PVDF was presented in Fig. 1, based on Koh et al. . The C–C double bonds were formed by dehydrofluorination of PVDF using strongly alkaline conditions combined with an acid acceptor (e.g. MgO).

WebFeb 20, 2024 · Generally, PVDF is highly resistant to both acidic and alkaline conditions; however, in highly alkaline solutions, PVDF deteriorates via dehydrofluorination and C–C double bond formation [33,34,35,36,37,38]. Therefore, determining the optimum conditions for alkaline hydrolysis of the PV backsheet such that the PET layer is effectively ... WebApr 14, 2024 · AMA Style.
