| Summary: | In this study, a thin, transparent and freestanding film of poly (methyl methacrylate)
(PMMA)/50% epoxidised natural rubber (ENR 50) blend was obtained by solvent casting
method. Various concentration of lithium triflate (LiCF3
SO3) salt was added into the
blend system. The films were then irradiated under UV light at 30 seconds. It was found
that the highest ionic conductivity obtained was 6.07 x 10-5 S cm-1 at room temperature
when the system was doped with 0.3g of LiCF3
SO3 salt. This was due to the presence of
highest number of free lithium ion that has been confirmed from the FTIR analysis where
the highest intensity of the -SO3 band was obtained. Furthermore, this system exhibited
the most homogeneous doped system when observed under optical microscope. |
