摘要：

The ionic conductive dendrimer electrolytes, prepared by the terminal alkali-metal (Li+, Na+, K+) carboxylation of poly(amidoamine) (PAMAM) of generation 2.5 and 3.5, exhibit a conductivity of 10(-5)-10(-6) S cm(-1) at 30 degrees C The temperature and frequency dependence of ion conductivity are investigated. It is found that the temperature dependence fits neither the WLF mechanism nor the Arrhenius equation; this is attributed to the unique molecular structure of the dendrimer. Blending of lithium carboxylated PAMAM with lithium perchlorate is carried out and results in improved conductivity. (C) 2000 Elsevier Science Ltd. All rights reserved.
