摘要
离子液体在质子交换膜发展领域是一类很有前景的非水质子载体,但在聚合物膜中的固化困难。本文通过在聚合物中加入表面介孔的中空二氧化硅并装载离子液体制备了二氧化硅/SPEEK/ILs复合膜。并研究了二氧化硅对离子液体流失、电导率等性能的影响。结果表明,随二氧化硅掺杂量的增多,质子传导率下降。无机物的引入阻碍了质子的自由跳跃通道,影响了质子传导率。但是二氧化硅掺杂量的增多显著减少了离子液体的流失。其原因可能是中孔氧化硅其内外表面含有更多的羟基与离子液体作用,并且水分子不容易带走空腔内的离子液体所致。
Ionic liquids in the field of proton exchange membrane is a promising anhydrous proton carrier. By adding the hollow mesoporous silica submicrospheres(HMSS) doping ionic liquid composite membrane, and to study the silica particles of ionic liquid loss, the proton conductivity and other properties. The proton conductivity will decrease with the increase of the doping amount of the silica particles. It will influence the free proton jump passages when introducing inorganic components. However, with the increase of the amount of silica, the loss of ionic liquids is significantly reduced, the reason may be that the inner and outer surface of mesoporous silica contain more hydroxyl and ionic liquid, and the water molecules are not easy to take away the ionic liquid in the cavity.
