PAA－PEG－盐复合膜导电性能研究

STUDY ON CONDUCTIVITY OF POLY(ACRYLIC ACID)-PLYETHLENE GOLYCOL-SALT COMPLEX MEMBRANE

研究了聚丙烯醚（ＰＡＡ）－聚乙二醇（ＰＥＧ）－盐复合膜的导电性能及其影响因素。研究结果表明，ＰＡＡ－ＰＥＧ－盐复合膜具有一定的导电能力。ＬｉＣｌ的加入量、添加剂的种类及其湿度、温度影响着复合膜的导电性能。随着ＬｉＣｌ含量的增加，电导率增大，但ＬｉＣｌ含量的增加是有限的；添加剂的加入可以大大提高电导率，而ＥＧ类的添加剂效果最好；复合膜的导电性能随着湿度、温度的升高而提高。

In this paper,the conductivity of Poly ( acrylic acid)(PAA)-polyethylene golycol(PEG)-salt complex membrane is studied. It is found that PAA-PEG-salt complex membrane exists conduction.And also, each factor affecting conductivity of complex membrane is discussed. With the increasing of LiCl content, humidity and temperature, the conductivity of complex membrane increases. Type and content of additives also affect the conductivity of complex membrane.
