Enhancment of ionic conductivity of polyethylene oxide(PEO) byincorporating polymethyl Methacrylate(PMMA) and modified graphenenanoparticles

The purpose of the study was to enhance the ionic conductivity of solid polymer electrolytes(SPE)by incorporating polymethyl Methacrylate(PMMA) and graphene nanoparticles into the polyethyleneoxide(PEO) matrix. The research also aimed to investigate the impact of three factors on thecrystallinity and ionic conductivity of the samples. The results showed that the level of PMMA massfraction significantly affected the degree of crystallinity, leading to the suppression of crystalformation in some samples. Among all the samples, Sample ۲ exhibited the highest ionicconductivity, with a value of ۲۰ mS.cm-۱, which is a very desirable amount for use in lithium batteries
