The effect of 3D printing parameters on electrochemical properties of heterogeneous cation exchange membrane

Popis výsledku v původním jazyce

The work focuses on the preparation of a heterogeneous cation exchange membrane by a 3D method - Fused Filament Fabrication (FFF) using a series of nozzles of various diameters (0.4––1.0 mm). Polypropylene random copolymer (PPR) as a polymeric binder was mixed with 50 wt.% of the selected conventional cation exchange resin and a filament was prepared using a single screw mini extruder. Then filament was processed by FFF into the membranes with a defined 3D structure. Electrochemical properties, morphology, mechanical properties, and water absorption properties were tested. Dependence of the tested properties on the used nozzle diameter was found. Both areal and specific resistances increased with increasing nozzle diameter. The same trend was also found for permselectivity. The optimal membrane with permselectivity above 90%, areal resistance of 8 Ω.cm2 and specific resistance of 124 Ω.cm2, was created using a nozzle diameter of 0.4 mm. Using new materials for 3D print of cation exchange membrane with production without waste. The possibility of producing 3D membranes with a precisely defined structure and using a cheap FDM 3D printing method. New direction of membrane formation. 3D printed heterogeneous cation exchange membranes were prepared which can compete with commercial membranes produced by conventional technologies with the possibility of prototyping and development in the field of simulations regards to time and cost savings
