摘要：
NASICON (NaTi2(PO4)(3) known as NTP) crystallites reinforcement in PEO-NaI polymer matrix leads to enhanced electrical transport. Thus, the effect of NTP ceramic filler particles on structural relaxation of polymer chains and conductivity relaxation has been studied using M ''-omega and sigma'-omega spectra. Temperature dependence of dc conductivity exhibits Vogel-Fulcher-Tammann (VFT) nature for PEO-NaI and Arrhenius behavior for NTP-polymer composite films. The conductivity behavior of two samples (with and without NTP) near glass transition temperature of PEO reveals that NTP crystallites facilitate electrical transport by providing conduction pathways. Due to significant conductivity enhancement near room temperature, the composites are found to be potential candidates for all-solid-state Na+ ion battery applications.
