Acrylates such as poly (methyl methacrylate) (PMMA) has been widely studied as a polymer electrolyte film due to its good mechanical stability towards lithium electrode. However, commercial PMMAs even at high molecular weight were not able to produce a flexible film due to its polar nature that is prone to form interchain crosslinking via hydrogen bonding. Therefore, in this study, the opportunity of the PMMA chains to form hydrogen bondingwashinderedbyincarcerating1-methyl-3-pentamethyldisiloxymethylimidazolium bis(trifluoromethylsulfonyl) imide, [(SiOSi)C1C1im][NTf2] during the polymerization of MMA via free radical polymerization. Interestingly, this newly synthesized PMMA containing IL (PMMAIL) produced flexible and transparent films with higher thermal stability and lower glass transition temperature as compared to the neat PMMA. The structure confirmation of this PMMAIL was elucidated using Nuclear Magnetic Resonance (NMR) and Fourier Transform Infrared spectroscopy (FTIR). The thermal properties of this PMMAIL were investigated using Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC). |
