| Summary: | In the present study, polyurethane (PU) had been prepared by using a different
content of Aluminium Oxide (Ah03) filler, in order to examine the filler addition
effect on the (SPE). The SPE has low ionic conductivity, so to enhance the
conductivity, the filler was added. The solid polymer electrolyte is synthesized by
solution casting technique. The SPE uses polyurethane (PU) as a host then doped
with lithium perchlorate (LiCI04), ethylene carbonate (EC) as plasticizer, and
aluminium oxide (Ah03) as filler. All solution use acetone as solvent. To
determine the ionic conductivity of SPE, the Electrochemical Impedance
Spectroscopy (EIS) was used. The highest conductivity is observed for the
composition PU-LiCI04-EC-30% Ah03 with a value of2.379xlO-7 S/cm at room
temperature. This is show that adding of filler can improved the ionic conductivity
because the formation of adhance sites and conduction pathways are improve the
for ionic transport by Lewis acid/base type interactions between the filler surface
groups and the ionic species. Then to determine the functional group of the
compound that contain in the SPE, its was characterized by using FTIR
instrument. Thermal analysis (TGA) proved the occurence of chemical interaction
of segmented PU solid polymer electrolyte. The conductivity is improve by mix
of plasticizer (EC) to decrease the crystallinity and increasing the amorphous
phase content of the SPE. The filler such as Ah03 is used to improve the
conductivity by encouraging the structure in the SPE. These properties exhibited
promising potential for ehhancement of SPE that giving focus on polyurethane |
