Characterization of pore morphology and performance of 3D-printed porous polymers for chromatographyDimartino, Simone (Avtor) Conti, Mariachiara (Avtor) Mravljak, Rok (Avtor) Picerni, Gabriele (Avtor) Pullen, James R. (Avtor) 3D printingcatalyst supportschromatographyligandsporosityThree-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.20252025-09-19 11:46:03Članek v reviji173656UDK: 678:66.081.3ISSN pri članku: 0888-5885DOI: 10.1021/acs.iecr.4c04337COBISS_ID: 244006403sl
