摘要
以N-乙烯基咪唑为原料设计合成溴化1-乙烯基-3-羧乙基咪唑功能化离子液体([HOOHEVIM]Br),并通过偶氮二异丁腈(AIBN)对[HOOHEVIM]Br进行引发聚合得到聚溴化1-乙烯基-3-羧乙基咪唑功能化离子液体(P[HOOHEVIM]Br).采用凝胶色谱仪,X-射线衍射仪,红外光谱(FTIR),核磁共振氢谱(~1H NMR),电化学工作站,电导率测试仪对其结构、聚合性与导电性进行测试与分析.结果表明:[HOOHEVIM]Br具有可聚性;聚合所得P[HOOHEVIM]Br的平均分子量为4.76×10~5,且为典型的无定形非晶结构并具有一定的离子导电性.[HOOHEVIM]Br的电化学窗口为2.75V.在30℃~50℃,[HOOHEVIM]Br的电导率随着温度的升高逐渐增大;随着浓度的增加,其电导率具有先增加后降低的趋势.
1-vinyl-3-Carboxyethylimidazolium bromide functionalized ionic liquid([HOOHEVIM]Br)was designed and synthesized with n-vinylimidazole as raw materials.The poly(ionic liquids)(P[HOOHEVIM]Br)was obtained by adding azodiisobutyronitrile(AIBN)to initiate[HOOHEVIM]Br.The chemical structure of [HOOHEVIM]Br was characterized by FTIR and ~1H NMR.[HOOHEVIM]Br has 2.75 Velectrochemical window,the electrical conductivity and the polymerizability.P[HOOHEVIM]Br is a typical amorphous structure and average molecular was 4.76×10~5.It was shown that[HOOHEVIM]Br has the good conductivity of the binary system.With the increase of concentration,it′s conductivity decreases after has been increa-sing.The electrical conductivity has agradually increase with the rise of temperature.
