Three-dimensional (3D)-printing technology holds the promise of fabricating ordered stationary phases with improved chromatography performances. The fabrication of large objects with nanoporous structures at a short printing time can be achieved by combining polymerization-induced phase separation and vat polymerization printing. This work aimed to study the influence of ink composition on the printing process and the resulting intrinsic pore morphology of 3D-printed stationary phases. Control of the phase-separation kinetics was attempted by varying the porogen-to-monomer ratio as well as the composition of the porogenic fraction. After assessing their printability, porous discs fabricated with different cyclohexanol-to-dodecanol ratios were characterized in relation to pore morphology, surface area, and permeability. Finally, monolithic discs were 3D-printed using a blend of 80% cyclohexanol and 20% dodecanol and functionalized with ion-exchange ligands to assess their performance with respect to other macroporous media.
