Abstract

Polydimethylsiloxane (PDMS)-based membranes containing silica for CO₂/N₂ gas separation were developed and fabricated via direct ink writing. Silica particles were used as fillers and thixotropic agent to enable 3D-printability of the PDMS ink. The printability of the inks was assessed by rheology, while the membranes were characterized by spectroscopy, microscopy, thermal analyses, and mechanical measurements. PDMS-based membranes showed high permeability for CO₂ gas, but with slightly low selectivity for CO₂/N₂ gas pair. The PDMS-silica membrane demonstrated the potential of 3D printing as an economical and sustainable fabrication method in developing materials for carbon capture applications. Graphical Abstract: [Figure not available: see fulltext.].
