文摘
- •
Tensile deformation of PVDF HF membrane was studied experimentally and numerically.
- •
Large tensile loading induces plastic deformation, resulting in pore growth.
- •
This leads to increase in water permeability.
- •
FEM mechanical model is developed to predict macroscopic and microscopic properties.
