제목 Gel Polymer Electrolyte based on Crosslinked Epoxy System for Wearable Electronic Device
초록 Polymer electrolyte has increasingly attracted attention to overcome safety issue in terms of no leakage of liquid electrolyte from the device. In this regard, gel polymer electrolyte(GPE)s which achieve high ionic conductivity and flexible properties represent promising candidate for next generation electrolyte. Generally, GPEs contain volatile organic compound(VOC)s from the organic solvent or vinyl monomer. In this way, epoxy is suitable material for reducing VOCs. Moreover, epoxy has high mechanical properties to maintained gel structure even with a large quantity of ionic liquid. In this work, we fabricated GPEs including improved characteristics such as flexibility and high ion conductivity. Diglycidylether of bisphenol, tri-block copolymer based amine hardner and triethylenetetramine are prepared with various ratio as a polymer matrix. Also, 1-ethyl-3-methyl imidazoliumbis (trifluoro methylsulfonyl)imide) (EMIM-TFSI) was added as both ion conductor and plasticizer.
