Abstract:

Two binary blends of tributylmethylammoniu bis(trifluoromethanesulfonyl)imide([TBMA][NTf2]) and ethylene-vinyl acetate copolymer(EVM), 1-butyl-3-methyl-imidazolium tetrafluoroborate([EMIM][BF4]) and EVM were prepared by melt blending. The blend of EVM and [TBMA][NTf2] is fully miscible and shows better anti-static electricity, while the blend of EVM and [BMIMBF4] is immiscible. In addition, TGA analysis indicated that [TBMA][NTf2] promoted EVM pyrogenation, while [EMIM][BF4] had little influence on the thermal stability of EVM. EVM filled with [TBMA][NTf2] is flexible at room temperature. The modulus of EVM/[TBMA][NTf2] composite is 0.58 MPa and the elongation at break is as high as 2997% with 20% mass fraction loading of ionic liquids.
