Description
Summary:► PVDF hollow fiber preserves its thermal and mechanical properties in light hydrocarbon environments. ► Aging in organic solvents changes the morphological properties of PVDF microporous membrane. ► Long-term organic solvent exposure results in the crystalline phase transformation from α- to β- or even γ-phase. In this work, PVDF hollow fibers were aged in different light hydrocarbon solvents (e.g. paraffins, olefins, and aromatics with carbon number
