摘要
采用物理混合的方法,以聚合物电解质PEG/LiClO_4为基体,埃洛石纳米管(HNTs)作为填料制备新型PEG基纳米复合聚合物电解质。通过差示扫描量热法(DSC)、广角X射线衍射(WXRD)、交流阻抗(EIS)、偏光显微镜(POM)等手段对样品进行了测试与表征,考察了一维纳米材料HNTs对聚合物电解质的结晶行为、结晶形貌和电化学性能的影响。研究表明,当HNTs的添加量不高于7%时,埃洛石的加入破坏了样品的结晶,使样品的电导率数值增大,在室温时的电导率值最高可以达到6.48×10~(-6)s/cm。但当埃洛石的含量超过7%时,聚合物电解质的结晶度反而增加。
The novel PEG-based nanocomposite solid polymer electrolytes(SPE) were prepared by physical mixing method and the PEG/LiClO_4 as the matrix and halloysite nanotubes(HNTs) as additives.The crystallization and electrochemical properties of electrolyte systems were characterized by using DSC, POM, WXRD, and EIS. The effect of the one-dimensional nanomaterials HNTs on the performance of SPE was disscused. It is found that crystallinity of SPE decrease but conductivity is improved with the increase of the content of HNTs when the amount of HNTs is not more than 7%. What's more, the ionic conductivity of SPE can reach 6.48×10~(-6)S/cm at room temperature. However, when the content of HNTs is more than 7%, the crystallinity of SPE increases and ionic conductivity decreases.
