Description
Summary:[Display omitted] •Gel polymer electrolytes with fluorinated monomer were prepared•Conductivity increases from co- SPMA, pure EOEMA, co- F17EMA•Best results for pure EOEMA with DEGDMA cross-linker•10% F17EMA gave best results with cross-linkers DEGDMA and TTEGDMA•With longer cross-links addition of fluorinated chains increases flexibility An extensive study on gel electrolyte systems based on 2-ethoxyethyl methacrylate (EOEMA) with various cross-link monomers is conducted with experimental techniques such as thermal analysis, stress-strain measurements and conductivity characterisation by impedance spectroscopy in order to clarify the influence of varying composition of the samples on their resulting properties. Furthermore, the addition of fluorinated side chains, used here predominantly with the aim of decreasing flammability of the ether-oxygen rich systems while boosting its ionic conductivity values, is investigated in terms of resulting mechanical, thermal and electrochemical properties.
