MECHANICAL RELAXATION TIME OF A TWO-COMPONENT EPOXY NETWORKLiClO4 POLYMER ELECTROLYTE*
The mechanical relaxation time of a two-component epoxy network-LiClO
4
system as a polymer electrolyte was investigated. The network is composed of diglycidyl ether of polyethylene glycol (DGEPEG) and triglycidyl ether of glycerol (TGEG)
wherein LiCIO
4
was incorporated and acts as both the ionic carrier and the curing catalyst. As the relaxation time is informative to the segmental mobility
which is known to be essential for ionic conductivity
the average relaxation times of the specimens were determined through master curve construction. Experimental results showed that the salt concentration
molecular weight of PEG in DGEPEG and DGEPEG/TGEG ratio have profound effect on the relaxation time of the specimen. Among these factors
the former reinforces the network chains
leading to lengthen the relaxation time
whereas the latter two are in favour of the chain flexibility and show an opposite effect. The findings was rationalized in terms of the free volume concept.
