Long-term stability of PVDF-SiO₂-HDTMS composite hollow fiber membrane for carbon dioxide absorption in gas-liquid contacting process.

ABSTRACT: Hybrid polyvinylidene fluoride-silica-hexadecyltrimethoxysilane (PVDF-SiO₂-HDTMS) membranes were fabricated via a non-solvent-induced phase-inversion method to create stable hollow-fiber membranes for use in the membrane contact absorption of carbon dioxide (CO₂). The surface properties, performance characteristics, and long-term performance stability of the prepared membranes were compared and analyzed. The outer surfaces of the prepared membranes were superhydrophobic because of the formation of rough nanoscale microstructures on the surfaces and their low surface free energy. The addition of inorganic nanoparticles improved the mechanical strength of the PVDF-SiO₂-HDTMS. Long-term stable operation experiments were carried out with a mixed inlet gas (CO
