摘要

Abstract

Acrylonitrile-sodium styrene sulfonate copolymer/layered double hydroxides nanocomposites were prepared by in situ aqueous precipitation copolymerization of acrylonitrile(AN) and sodium styrene sulfonate(SSS) in the presence of 4-vinylbenzene sulfonate intercalated layered double hydroxides(MgAl-VBS LDHs) and transferred to acrylonitrile-styrene sulfonic acid(AN-SSA) copolymer/LDHs nanocomposites as a proton-conducting polymer electrolyte.MgAl-VBS LDHs were prepared by a coprecipitation method

and the structure and composition of MgAl-VBS LDHs were determined by X-ray diffraction(XRD)

infrared spectroscopy

and elemental analysis.X-ray diffraction result of AN-SSS copolymer/LDHs nanocomposites indicated that the LDHs layers were well dispersed in the AN-SSS copolymer matrix.All the AN-SSS copolymer/LDHs nanocomposites showed significant enhancement of the decomposition temperatures compared with the pristine AN-SSS copolymer

as identified by the thermogravimetric analysis.The methanol crossover was decreased and the proton conductivity was highly enhanced for the AN-SSA copolymer/LDHs nanocomposite electrolyte systems.In the case of the nanocomposite electrolyte containing 2% (by mass) LDHs

the proton conductivity of 2.60×10

was achieved for the polymer electrolyte.
