| 논문초록 | A critical issue for polyamide (PA) thin film composite membranes for desalination applications is to improve permeability and salt rejection for performance. Unlike commercial techniques for PA thin film fabrication which are generally used interfacial polymerization at the liquid-liquid interface, in this work, we formed PA Langmuir monolayers at the air-water interface by interfacial polymerization, followed by deposition on a support using the Langmuir-Schaefer technique. This technique facilitates controlling thickness and roughness in a nanoscale and forming nanochannel structures from PA multilayers through repeated deposition. Neutron reflectivity technique provided the evidence of presence of nanochannels in the PA multilayer. UV irradiation also applied to Maintain the nanochannels and nanowrinkles which function as water permeable sites. Due to these structural benefits, we increased permeability by up to 200% without loss of salt removal performance. |
