Optimisation of thin film composite nanofiltration membranes based on laminated nanofibrous and nonwoven supporting material

Popis výsledku v původním jazyce

The electrospun nanofibrous membranes are one of the emerging technologies for membrane filtration;however, the applications of nanofibrous membranes hindered by their low mechanicalstrength and lab-scale production method. This work describes the fabrication of composite membranesconsisting of the following three-layer system: a nonwoven part as the supporting material,a nanofibrous scaffold as the porous layer, and an active barrier layer. The nonwoven part and thenanofibrous scaffold were laminated together to achieve the required mechanical strength and adhesion.Formation of the active barrier layer was carried out by optimising four parameters: the monomersolution concentration, the reaction time for monomer polymerisation, the drying time and thepost-treatment temperature. At each step of the process, one of the optimum conditions, indicated byfiltration performance and the investigation proceeded to the next step. The filtration performance ofthe fabricated thin film nanofibrous composite (TFNC) membranes was done by the dead-end cell.The TFNC membrane based on m-phenylenediamine monomers showed a high rejection (93.5%) ofNaCl ions at a low flux. The flux performances of the piperazine monomer-based TFNC membranesshowed high MgSO4 salt rejection (95.6 %) and flux at the same time.
