제목 Hybrid Boron Nitride Nanotube Membrane as an Ion-permeable Separators
초록 Boron nitride nanotube (BNNT) is an emerging nanomaterial having unique properties such as high mechanical properties, high thermal conductivity as well as high thermal and chemical stability. The membrane with BNNTs are, therefore, perfectly suited for high temperature ion-permeable separators for energy applications. In this work, ultra-thin and high density membrane with several nanometer-sized pores were fabricated using poly(4-vinylpyridine) (P4VP), efficiently dispersing and strongly adsorbing on the surface of BNNTs. The P4VP, then, crosslinked with 1,10-dibromodecane via quaternization. The quaternization reaction, systematically studied via XPS, greatly affected to the interfacial property of the membrane such as wettability and water permeability. Furthermore, via infiltration of silica precursors into the quaternized P4VP, a hybrid membrane with silica matrix was fabricated after calcination.
