An experimental study on the filtration performance of a poly-alpha-olefin-compatible expanded polytetrafluoroethylene high-efficiency particulate air filter

South African Journal of Chemical Engineering, 2022
Filter media made of expanded polytetrafluoroethylene filters are known to be incompatible with poly-alpha-olefin or any oil-based challenge particles, and thus, filters made of expanded polytetrafluoroethylene had limited use in pharmaceutical ...

Unified throughout‐pore microstructure enables ultrahigh separator porosity for robust high‐flux lithium batteries

Electron, 2023
With small thickness, commercial polyolefin separators own low porosity to ensure sufficient thermomechanical properties, resulting in tortuous and enlarged Li+ diffusion pathways that induce large overpotentials and detrimental dendrite growth.
