Characterization of PVDF Hollow Fiber Membrane for CO2 Stripping by Atomic Force Microscopy Analysis

Microporous polyvinylidene fluoride (PVDF) membranes with various concentrations of lithium chloride additives were prepared for CO2 stripping test. Physical membrane characterizations such as atomic force microscopy analysis, gas permeation, contact angle measurement and liquid entry pressure were...
