리튬 회수용 크라운 에테르가 함침된 고분자 나노화이버 분리막 개발
로렌스 림주코,그레이스 니솔라,레이 토레호스,하나 게브리찌아버,이성풍,서정길,정욱진 한국막학회 2016 한국막학회 총회 및 학술발표회 Vol.2016 No.05
Synthesis of Li+-selective 14-crown ether (CE) having rigid and bulky subunits was reported. CE-poly(vinyl alcohol) (PVA) dope solutions were electrospun. CEs were immobilized on PVA matrix via acid-catalyzed acetalization using novel aerosol method. Structures of new compounds and their immobilization to PVA were confirmed and characterized. Adsorption experiments show superior lithium capacity and selectivity among previously reported solid-supported CEs. Dihydroxy-dibenzo-14-crown-4 ether-PVA nanofiber membrane showed superior performance. This work was supported by Basic Science Research Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Science, ICT and Future Planning (2015R1A2A1A15055407) and by the Ministry of Education (No. 2009-0093816).
