New Inorganic-Organic Polymer Electrolytes based on Polyethylene Glycol 400 and Aluminum Isopropoxide: Conductivity Mechanism,Thermal Stability and Morphology (part II).

摘要

In this report are presented accurate studies on the morphology,thermal stability and electrical spectroscopy of eleven aluminum containing hybrid inorganic-organic polymer electrolytes of the ORMOCERs-APE type with general formula {Al[(CH_2CH_2O)_(8.67)]]_(rho)/(LiClO_4)_z}_n,where 1.85<=rho<=2.24 and 0 <=z <=1.06 (see part I).These materials were prepared by means of a policondensation reaction between a PEG400/(LiClO_4)_x solution with 0 <=x <=4.890.10~(-1) and Aluminum isopropoxide.The polymers thus obtained,basically consist of three-dimensional networks with aluminum atoms bridged together by polyethereal chains.Scanning electron microscopy showed a solid-plastic appearance and a smooth texture on the surface of the bulk material.
