Is hydrocarbon a polymer
Witryna9 kwi 2024 · PVDF is a linear fluorinated hydrocarbon polymer that crystallizes in different structures (e.g., α, β, γ, δ, and ε phases) [43]. The α phase is the most common structure, in which fluorine and hydrogen atoms alternately appear on the carbon chain, resulting in an overall dipole of zero (non-ferroelectric).
